I've installed Matlab on a linux(Fedora) os. No error message appeared. I went on the installation folder and ran matlab from the terminal with

./matlab

Every function works well, but when I invoke some graphic functions like plot or surf, the system stops to work like when there is an infinite loop, and i really don't know what to do. For example

>>x=[0:0.1:10];
>>plot(x);

It doesn't work.I tried with

get(0,'DefaultFigureVisible')

and the result is 'on'. I also tried 'plottools' but everything concerning graphics functions don't work

This could be because of graphics driver related errors. Please provide the following information

1)Does your code run without error when using software OpenGL? you can open MATLAB in software OpenGL mode using 'softwareopngl' flag.

./matlab -softwareopengl

2)Also, Please provide the output of opengl info for all computers you have tested your code on. Try running this command

>> opengl info

on MATLAB command prompt. What is the output ?

thank you for your answer. switching on software opengl works. I found another solution, installing bumblebee and using the command

>> primusrun matlab

and it worked, but bumblebee started to give problems with KDE, so i think your solution is better. Anyway, now the output is:

>> opengl info
                        Version: '2.1 Mesa 10.5.2'
                         Vendor: 'Brian Paul'

MATLAB on OS-X and Linux is not intended to be executed directly from its binary: it is intended to be executed from a framework (OS-X) or from a shell script that sets up appropriate environment variables (Linux)
