Dear Community,

is it possible to change the default warning settings? Even when I start MatLab I receive one particular warning message! When I turn this warning off (using warning('off',id)) it is just for the current session! When I restart MatLab this message appears again!

Can anyone help me with this issue?

Thanks, Robert

You can edit your startup.m

However, if you are receiving a warning on startup then it is possible that the warning would be issued before startup.m would be read. What warning is it you are encountering?

Hello - this is the warning from the Command Window:

Warning: MATLAB has disabled some advanced graphics rendering features by switching to software OpenGL. For more information, click here.

Using warning('query','last') results in the prompt:

warning('query','last') The state of warning 'MATLAB:hg:AutoSoftwareOpenGL' is 'on'.

在 MATLAB Online 中打开

http://www.mathworks.com/help/matlab/ref/opengl.html

opengl('save','software')

See also http://www.mathworks.com/help/matlab/ref/opengl.html#buwqhi1-8 about what is being disabled.

You could also try

opengl hardwarebasic

to see if that works for you.

Hy,

the command opengl('save','software') did work because it changes the default starting setting for opengl to software! Thanks for that!

What I originally wanted (to disable this warnning) is not solved due that - but I tried a lot to find the m-file where I can change this setting, but as you know I failed ´to find that :-)

My suspicion is that this warning was being sent before your startup.m would be executed. I do not have MATLAB installed on that operating system to test with.
