I need to run a function from a software package that is written in a .p file. To run it on a cluster, I need to start matlab with the following options:

matlab -nojvm -nodesktop -nosplash -nodisplay -singleCompThread

The .p file attempts to make figures which cause matlab to crash due to nojvm. Is there anyway to prevent the figure creation without being able to edit the source code?

Thanks in advance!

The whole point of p code is to prevent the end user digging around, so perhaps the writer of the code used the builtin() function to ensure built-in functions are called.

The inconsistent behavior is odd. I wonder whether it has something to do with the OS.

My guess at the moment would be that it has to do with Answers running in a LiveScript environment. LiveScript must be implicitly intercepting figure() so that it can inline figures.

I did get this to work by using a brute force version of replacing the built in functions, as suggested in the comments.

I created dummy versions of the graphics, graph2d, graph3d and specgraph folders. Replaced all the functions, so no subsequent plot call of any kind would throw an error. Then removed the built in versions from the path and added my dummy versions.

    rmpath(genpath('/usr/local/MATLAB/R2021b/toolbox/matlab/graph2d'))
    rmpath(genpath('/usr/local/MATLAB/R2021b/toolbox/matlab/graphics'))
    rmpath(genpath('/usr/local/MATLAB/R2021b/toolbox/matlab/specgraph'))
    rmpath(genpath('/usr/local/MATLAB/R2021b/toolbox/matlab/graph3d'))
    addpath(genpath('./graphics'));
    addpath(genpath('./graph2d'));
    addpath(genpath('./specgraph'));
    addpath(genpath('./graph3d'));
