Running matlab from linux platform with openGL
显示 更早的评论
Hi,
I'm currently running matlab from the linux command line as follows:
>> opengl software
>> xyz.m
I had found out that using the openGL command enabled my figures to display otherwise the code would break since linux does not like graphical intensive procedures.
Now, I was wondering if I could avoid typing in this openGL command everytime I run my code by building it into the alias that I made for opening matlab from the linux command line. I am thinking something like this:
alias intmat = "/opt/matlab/R2011a/bin/matlab -nosplash -nodesktop -opengl"
So every time I invoke matlab it should be ready to handle graphics such as figures. The last switch "-opengl" won't work I think. Any suggestions? Is this even possible?

First, it seems odd that you need to switch to software rendering. You should contact technical support so that they can look into making hardware rendering work.
To answer your question you can put opengl software in a number of places. The most common would be in startup.m This file is run at load time if MATLAB can find it on the path. Since this seems to be system dependent, a better place might be to edit matlabrc.m. This will affect all users independent of their startup preferences.

You'll have to use the system command to issue a command to the command line (otherwise it will be interpreted as a matlab command), so the line in your startup.m file should read;
% Switch to software mode in opengl
system('opengl software');

Kevin's comment is incorrect. The command you want is a MATLAB command, not a system command.

My guess is that you didn't put it in the "correct" startup.m. That is why I suggested to edit matlabrc.m

Whoops, yeah my apologies. Walter's right - I misinterpreted what you meant when you said "running linux from the command line".
