How to call Matlab functions from linux command line ?

Question

Basically I have a m file which looks like

function Z=myfunc()

% do some calculations

dlmwrite('result.out',Z,',');

end

What I want is just execute it from command line without getting into Matlab. I tried several options (-nodisplay -nodesktop -nojvm -r ....), none of them worked. I end up getting into Matlab and have to type "quit" to exit.

Anyone know the solution??

Thanks in advance.

How do I run MATLAB in batch mode on a UNIX machine?

Answer 2

Matlab can run scripts, but not functions from the command line. This is what I do:

matlab_batcher.sh:

#!/bin/sh

matlab_exec=matlab
X="${1}(${2})"
echo ${X} > matlab_command_${2}.m
cat matlab_command_${2}.m
${matlab_exec} -nojvm -nodisplay -nosplash < matlab_command_${2}.m
rm matlab_command_${2}.m

and call it by entering:

./matlab_batcher.sh myfunction myinput

Answer 3

matlab -nosplash -nodesktop -logfile remoteAutocode.log -r matlabCommand

make sure matlabCommand has an exit as its last line.

Answer 4

nohup matlab -nodisplay -nodesktop -nojvm -nosplash -r script.m > output &
