Press the file explorer button and add the Dbg_sim.ini file, which is in the first project directory as the debugger initialization file. Type the file name; in this case type cat1.m and click Save.
Create a new M-file for the, Up and Running with AutoCAD 2012 (Second Edition). Secondly, the runtime file recorded two-cycle (precycle and postcycle) three-phase current signals of the main feeder and three DGs and referred to as second category data. Both approaches recorded three-phase fault current data for two-cycle (one precycle and one postcycle) with a sampling frequency of 10 kHz (~167 samples/cycle). The example presented here is to demonstrate how quickly we can run the code using Jupyter notebook. Lets modify our plot_patient1 script so that it creates and saves sub-plots, Now the debugger has an additional instruction trace window. Much more powerful than scripts are functions, which allow the user The script is created using edit command in Matlab. well waste time rewriting commands. Hadoop, Data Science, Statistics & others. The trace buffer is then only limited by the size of the PC hard disk. The easiest way to run Python code is through the Python shell or IPython shell (which stands for Interactive Python). It is perhaps the simplest type of programming you can do. To launch the IPython shell, we begin by typing ipython in a terminal (see Fig. The script for this is shown below. MATLAB displays the value of the fact_of_n variable in its Command Window as shown. to newdir.
You can execute a cell by clicking the evaluate-cell button or the evaluate-cell-and-advance button . So far, weve typed in commands one-by-one on the command line In the above example, the green text denotes author comments. A MATLAB script Using the Python shell or IPython shell. The raw opcode is then displayed as an assembler mnemonic. Write the code for drawing a sphere of radius Rad. A new script can be created by clicking [Crtl]+[N] or by clicking the new script button in the Home toolbar. When you refer This is the same script file that was used with the standard Ulink2 debugger. Similarly to option 1, the active script in the Editor window will run if multiple scripts are open. Figure 1.7. In Chapter 8, we will see how to get this information from a real microcontroller. This is because the script shares the workspace with the current directory, and it is good practice to make sure that your script file is not using variables from old MATLAB sessions. Figure 1.10. You can get MATLAB to run the commands in the script by typing in the name On the other hand, it is worth noting that the available physical PMU in the Power System Research Lab at King Fahd University of Petroleum and Minerals (KFUPM) is limited to measuring 12 signals only. The factorial of 3 is 321=6, and so on. The simulator also boasts some advanced analysis tools including trace, code coverage, and performance analysis. Functions are most useful when a task needs to be done many times. Lets write an H1 line at the top of our script: We can then get help for our script by running. The following screenshot is an example script that calculates the volume of sphere of radius 4. The performance analysis window shows the number of calls to a function and its cumulative runtime. This is another plus of writing scripts: you can comment
As this example shows, the commands in the script can refer to the Figure 1.8. workspace (notice the reference to N and w in plotsin.m). MATLAB goes to the factorialN.m file and stops before executing the first command in the factorialN function, which is line 4 here as shown in the following figure. Fig. fcn.m (the name of the function within Matlab is the name of the However, the content of the variable should be 2. In this example will plot a sine wave and a cos wave in the same plot using script. A cell is a piece of script code that can be run individually. Let us proceed to debug our program in a step-by-step manner. You should find that, unexpectedly, it is still 0. To learn how to debug both script files and functions. Save the file with the name factorialN.m. A = linspace (-pi, 2*pi); back to it after a while. In order to debug a function, it must first be called from a script M-file. Try this out with an AutoCAD file that has a bunch of layers. Code cells can be created by double commenting, or using two %%. Press F10 to execute the command in line 3. this file is visible to MATLAB. As the simulation runs, we can see the state of the port pins. Trevor Martin, in The Designer's Guide to the Cortex-m Processor Family, 2013. Name the script file call_add2.m. Script files share their workspace with the current directory, so be careful that variables assigned in the script file are not overwriting other variables with the same name. and then on Add with Subfolders. click on Set Path, Execute the cells one at a time using cell mode. 11.8 presents the experimental setup used for test feeder modeling and data recording processes. If the pins are configured as inputs, we can manually set and clear them by clicking the individual Pins boxes. Then, in order to run the EditorExample.m it is necessary to change the current directory to the F:\MATLABforQASciences\Chapter_5_qa as described above, and to type and enter the file name (without the m-extension) in the Command Window: The result of the sample size calculations using the commands that were saved in the script file and displayed in the Command Window. This can be done in the project menu by right clicking the project name and selecting Options for Target or by selecting the same option in the project menu from the main toolbar. to a file (either code or data), MATLAB will search all the directories in the path The process of debugging a function is probably best explained by way of an example. 1.6). To change the The code can be a single stepped C or assembler line at a time, run at full speed and halted. and typing them in shouldnt take put those commands in a script called plot_patient1.m, Run the script M-file callfun.m. command line, we can Now create a new M-file for the factorialN function. The first help text line (known as the H1 line) To perform this task, click on the icon (indicated by the arrow in the following screenshot) and choose the location where you would like to save the folder Lesson 2. to get MATLAB to do things for us. after we are doing plotting on it - the same as we would close It is likely that you will halt in a delay function. The same commands are available through the debug menu, which also shows the function key shortcuts that you may prefer. axis equal. To step to line 4, press F10, which is the short-cut key for Step. Now exit MATLABs debug mode. This is not to be confused with cell arrays. The value of the fact_of_n variable should have been set to 1 if the program is going to work properly. Then we run a Python command by typing it into the shell and pressing Enter. its sometimes useful to turn off their visibility as MATLAB plots them. For the all options, the script file must be located in the Current Folder. We do this by adding directories to the MATLAB path. 11.6. Type the following code in the file editor. Choose a suitable name for the file, as you learned how to do in Lesson 1.2, and then save it. These windows allow you to view local variables, global variables, and the raw memory. Selected current signals from the RSCAD/RTDS environment were sent through the GTAO card to the PMU and were saved using the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) program. or block of comments in a script or function is used by MATLAB as the By closing this banner, scrolling this page, clicking a link or continuing to browse otherwise, you agree to our Privacy Policy, Explore 1000+ varieties of Mock tests View more, Special Offer - MATLAB Certification Course Learn More, 3 Online Courses | 1 Hands-on Project | 8+ Hours | Verifiable Certificate of Completion | Lifetime Access, R Programming Training (13 Courses, 20+ Projects). Besides, each fault was applied for four cycles on the modeled test feeder in the RSCAD/RTDS environment. The IPython shell is more powerful than the Python shell, including features such as Tab autocompletion, color-highlighted error messages, basic UNIX shell integration, and so on. The results of running this script M-file should be an output value of 6, the factorial of 3, where 3!=321. The path is a list of directories MATLAB will search through to locate The current location of the program counter is shown by the yellow arrow in the left hand margin. edit drawWaves The command window allows you to enter debugger commands to directly configure and control the debugger features. syms x your code to make it easier to understand when you come (without the extension), those commands are executed as if they 1.10). Matlab Script is a sequence of various commands, which are most likely used to represent some program and are executed in the same way as a program or single command in Matlab command window.
The unlimited trace option allows you to stream every instruction executed to a file on your PC hard disk. You can call a function from a script file. When the script file is run, MATLAB executes the instructions in order as if you typed them into the command prompt one at a time. Run Hello World in IPython shell by typing the command. However, it is useful if you are able to read the low level assembly code to see what the compiler is doing. In this study, data isrecorded using two different approaches.
Currently, the Use Simulator option is set. Type your code in the cell and press Shift + Enter to run the cell; the results will be shown below the code (Fig. If the logic analyzer window does not open automatically select it from the toolbar. A breakpoint is marked by a red dot. Next, we will call this script. While creating a script, we must save it as .m extension and keep the file name the same as the name of the script. Click on Make New Folder. The next step is to save the script file to a specific folder. (See help path to learn how to add a directory to this list.) When the ULINK2 trace tool is connected, you have the option to enable the ETM trace. Check the current MATLAB folder; if the file is not in it, a directory with this file should be set up as described above. The third way to run Python is through Jupyter Notebook, which is a very powerful browser-based Python environment. We will discuss this in details later in this chapter. Go to the file callfun.m. By signing up, you agree to our Terms of Use and Privacy Policy. Click OK to quit back to the Vision editor. Bins = Col/100; This will open a window that displays the current state of the microcontroller IO Port B. While the above example is quite simple and easy to understand, as the programming code becomes more and more complex, it becomes even more necessary to ensure that a script is well commented. is just a text file with a .m extension. Set a breakpoint on the main while loop in blinky.c. Firstly, it employed an RSCAD built-in PMU to record the magnitudes and the phase angles of three-phase currents (IA, IB, and IC) and associated sequence currents (I1, I2, and I0) of eight selected branches (650 to 632, 632 to 671, 632 to 633, 632 to 645, 671 to 680, 671 to 684, 684 to 652, and 671 to 675) as referred to first category data. Unlike a function, a script file shares its workspace with the current directory. The MATLAB debugger has the ability to track bugs inside functions. It is worth mentioning that this chapter applied seven different types of faults (AG, BG, CG, ABG, BCG, CAG, and ABCG) on 21 locations of the modeled test feeder as depicted in Fig. Weve written
