MATLAB: Dos command line invocation

dos batch script command lineMATLAB

Is there a way to just call matlab from a dos command, pass it a .m file, have it execute that .m file and exit quitely, possibly only returning a completion status?

Best Answer

There are a number of options you can pass. In your case, I think you would use -minimize, -nosplash and the path to the m-file you wanted to run.

All the options are documented here:

The completion status can be a bit tricky, as I'm not 100% sure that %ERRORLEVEL% will be set correctly if there's an error in your program, since MATLAB may have "exited correctly". You would need to experiment with that, but it should be easy to test.

MATLAB: Responding to DOS prompt from MATLAB command line

Another approach with my example using File=input() works.

Assume the file name you entered through prompt is called MyText.txt.

Please create another text file first, the file is called input.txt, its content is a single line of text: MyText.txt

Run the following in Windows command line, no problem

TestCommandLine <input.txt

Run the following in Matlab command line, no problem

system('TestCommandLine <input.txt')

Can you try this and try the same with your executable?

MATLAB: How to call MATLAB from a Windows command prompt or a Linux Shell and not return control until MATLAB has finished executing

On Windows, you can use a batch file that calls MATLAB in order to achieve this. Batch files keep control over the command prompt until all the calls have finished executing.

Below are the steps to do so:

1. Create an empty batch file called, for example, mymatlab.bat

2. The contents of the file should be the following (use the correct path for your MATLAB installation):

echo before
C:\MATLAB\R2008a\bin\win32\matlab.exe %1 %2 %3 %4 %5 %6 %7 %8 %9
echo after

The symbols %1 to %9 represent the number of parameters that can be passed to the batch file, a maximum of 9. So when you call the batch file as follows:

mymatlab.bat -nosplash -nojvm /wait -r "ver;quit"

The actual command that will be executed is:

C:\MATLAB\R2008a\bin\win32\matlab.exe -nosplash -nojvm /wait -r "ver;quit"

Notice that the word "before" appears before MATLAB is launched whereas the word "after" does not appear until MATLAB exits.

----------------------------------

To achieve the same effect on Linux, instead of using % symbols to represent shell script input arguments use the dollar sign ($):

The script should be similar to the code below:

echo before
/myMATLABpath/matlab $1 $2 $3 $4 $5 $6 $7 $8 $9
echo after

Now if you execute the shell script as follows:

 /myfolders/myShellScript -nodesktop -nosplash -r "ver;quit"

Then you will notice that the word "before" will be printed in the UNIX shell whereas the word "after" will not appear until after MATLAB exits.
