MATLAB Installation Guide for Unix

Solving File Permission Problems

During installation, certain files are checked for world (or other) access permissions. If any of the permissions are incorrect, you should exit from the installation procedure, set the user mask (umask) correctly, and then reinstall MATLAB.

During installation, the installer checks the value of the user mask. If the value of the user mask is outside of the correct range, you are prompted for an alternative. This value determines the permissions of any files created during the installation. For MATLAB, the suggested file permissions are

Scripts and directories	chmod 755
Executable images	chmod 755
All other files	chmod 644

Problems Opening the Display

If, after starting OpenWindows or Motif, the installation program outputs the Can't open display error message, enter the following command at the UNIX prompt:

• xhost +x
  

Then run the installation procedure for your platform:

• install* (Sun, Compaq, IBM, SGI, and Linux platforms)
  INSTALL* (HP platform)
