There is no uninstaller for MathWorks products on Linux. To remove MATLAB, you simply need to delete the MATLAB installation following the instructions below:
1. Remove the entire root directory using the 'rm -rf' command, ex:
[root@localhost ~] rm -rf /usr/local/MATLAB/R2010b
2. Remove any symlinks to binaries on the path, ex:
[root@localhost ~] rm /usr/local/bin/matlab /usr/local/bin/mcc /usr/local/bin/mex /usr/local/bin/mbuild
