Matlab prompt

The MATLAB prompt is that place where you type formulas, commands, or functions or perform tasks using MATLAB. It appears in the Command window. Normally, the prompt appears as two greater-than signs (>>).However, when working with some versions of MATLAB, you might see EDU>> (for the student version) or Trial>> (for the trial version) instead. No matter what you see as a prompt, you use it to know where to type information.You can utilize a useful command known as clc. Try it now: Type clc and press Enter at the MATLAB prompt. If the Command window contains any information, MATLAB clears it for you.The userpath() function is called a function because it uses parentheses to hold the data — also called arguments — you send to MATLAB. The clc command is a command because you don’t use parentheses with it. Whether something is a function or a command depends on how you use it.The usage is called the function or command syntax (the grammar used to tell MATLAB what tasks to perform). It’s possible to use userpath() in either Function or Command form. When you see parentheses, you should expect to provide input with the function call (the act of typing the function and associated arguments, and then pressing Enter).MATLAB is also case sensitive. That sounds dangerous, but all it really means is that CLC is different from Clc, which is also different from clc. Type CLC and press Enter at the MATLAB prompt. You see an error message. (MATLAB will also suggest the correct command, clc, but ignore the advice for right now by highlighting clc and pressing Delete.)Next, type Clc and press Enter at the MATLAB prompt. This time, you see the same error because you made the “same” mistake — at least in the eyes of MATLAB. If you see this error message, don’t become confused simply because MATLAB didn’t provide a clear response to what you typed — just retype the command, being sure to type the command exactly as written.Notice also the “Did you mean:” text that appears after the error message. Normally, MATLAB tries

NOTE: This command is to be used for R2019a and prior. If you are using R2019b and newer, please see this article.What is Parallel Server License Check?The 'dmlworker' MATLAB start up flag can be used to ensure that the licensing and installation for MATLAB Parallel Server is configured correctly on your cluster. This is useful as MATLAB cannot be invoked directly if licensed as part of an MATLAB Parallel Server cluster.This will also test to see if MATLAB is crashing on startup in your cluster. To test this, go to one of the worker nodes in the cluster and open up a Command Prompt or Terminal window, then run the following commands:Windowscd $MATLAB/binmatlab.exe -dmlworker -nodesktop -logfile C:\Temp\output.txt -r "ver;exit"Mac/Linuxcd $MATLAB/bin./matlab -dmlworker -nodisplay -logfile /var/tmp/output.txt -r "ver;exit"(where $MATLAB is the installation folder for MATLAB on the cluster)These will generate an output.txt file (at your specified location) that contains the 'ver' output for the worker node. If the log file contains a license manager error, this is the issue. In that case, check MATLAB Answers for the license manager error number and take the appropriate action to resolve the license error before proceeding.If you do not receive a License Manager error, confirm that "MATLAB Parallel Server" appears in the 'ver' output as an installed product.

You can use the Simulink® debugging programmatic interface to run a simulation of a model one method at a time. Blocks in Simulink are implemented as a set of methods that are called by the solver at specific times during each time step. Using breakpoints, you can control when the simulation pauses and examine the execution results to trace behavior in your model to specific blocks, parameters, or connections. You can set breakpoints for specific conditions throughout the model, such as zero crossings, or on block methods and signals.NoteTo debug a simulation using the Simulink debugging programmatic interface, you must start the simulation using the sldebug function or using the sim function with the debug name-value argument.The Simulink Editor offers many of the same capabilities in the programmatic interface.Use Simulink Debugging FunctionsWhen you programmatically debug a simulation, you start the simulation using the sldebug function. After you call the sldebug function, the MATLAB® command prompt becomes the sldebug command prompt. Instead of >>, you see (sldebug @0): >>. To control the debugging session, enter debugging commands in the MATLAB Command Window, at the sldebug command prompt.For ease of use, the Simulink debugging programmatic interface accepts abbreviations for the debugging functions. For example, to call the step function, instead of entering the command step, you can enter the command s.Use MATLAB FunctionsYou can enter any MATLAB expression at the sldebug command prompt. For example, suppose you are paused on a breakpoint and the simulation logs the time and output of your model as tout and yout. You can enter this command at the sldebug command prompt to create a plot.Some MATLAB functions have the same name as or a similar name to a function in the Simulink debugging programmatic interface. To view the contents of a variable or to call a function with a name that partially or entirely matches the name of one of the Simulink debugging functions, use the eval function. For example, suppose the workspace contains the variable s. To display the contents of the variable instead of calling the step function, use this command.Understand Block and Method IDsSome of the debugging functions and messages use a numeric block ID or method ID to refer to a specific block or method in the model. Block IDs and method IDs are numeric values that the software assigns to each block and method in the simulation during run time.The software assigns block IDs while generating the sorted order and execution list for the model during the compilation phase of the simulation. A block ID has the form (t)s:b, where t is an integer that identifies the task in which the block executes, s is an integer that identifies the system

That contains three edit fields of different widths.x = inputdlg({'Name','Telephone','Account'},... 'Customer', [1 50; 1 12; 1 7]); Interpret prompt Value with TeX Interpreter Create a dialog box that uses the options structure to render the prompt using TeX markup. Define the options for the dialog box by specifying: A prompt that includes the \theta character sequenceA dialog titleA default input value of 30An edit field height equal to 1 row of text and width equal to 40 character unitsTeX as the interpreterThen, create the input dialog by specifying these options.prompt = {'Enter a value of \theta (in degrees)'};dlgtitle = 'Theta Value';fieldsize = [1 40];definput = {'30'};opts.Interpreter = 'tex';answer = inputdlg(prompt,dlgtitle,fieldsize,definput,opts);Convert Input to Numeric Values Users can enter scalar or vector values into inputdlg text edit fields. MATLAB® stores the input as a cell array of character vectors. Convert a member of the input cell array to a number, using str2num.
