run matlab function with arguments on linux terminal
显示 更早的评论
Hello, do you have any idea how to run matlab functions from the linux shell specifying their arguments? what i tried was: { matlab -r myfunction(argument1,argument2) } but it doesn't work oO

Hi Ayoub, what is the purpose of the "-r" and also how do you know what to even type on the terminal (what should I look up for this?) Thanks!

"-r" followed by something indicates that MATLAB should take what follows as a command to run.

matlab -r 'myfunction(argument1,argument2)';
Or safer:
matlab -r 'try myfunction(argument1,argument2); catch; end; quit'

Adding to Walter's answers above..
you could also try
matlab -r -nodisplay -nojvm 'myfunction(argument1,argument2)';
-no display removes the Xdisplay and -nojvm starts matlab without hte Java virtual machine.
you could also try
matlab -r -nodesktop -nojvm 'myfunction(argument1,argument2)';
or use the abovewith the try-catch loop as suggested by Walter..

Hi,
I have a similar question regarding running matlab with arguments on linux terminal. I want to run my matlab code on GPU and if I set the number of GPU manually the code run, while if i give the number of GPU as a variable of my function I get the following error:
Not enough input arguments.
This is how I run the function:
matlab -nodesktop -r "nodes=2; averaging_filament='single_filament_averaging_reikaparam_is40'; folder='polarity_TRIAL'; run streamline_tomo_GPU.m" ;
and inside the code:
GPU=[nodes];
No idea why is it not running :(

I recommend converting streamline_tomo_GPU into a function with nodes as its parameter. Alternately, convert
GPU=[nodes];
to
GPU=evalin('base','nodes');

According to the matlablinux documentation, you should not use the option
-r
but instead use the option
-batch
I've tested this on MATLAB R2018b.
The command
matlab -nodisplay -nojvm -r 'somefunction(someargument); anotherfunction(anotherargument);'
did not run anotherfunction(). It did when I changed -r to -batch!

-batch is a new option as of R2019a. -r still works.
