Why am I missing files from my MATLAB 6.5.1 (R13SP1) installation on Linux?

Why am I missing files from my MATLAB 6.5.1 (R13SP1) installation on Linux?

I have recently installed MATLAB 6.5.1 (R13SP1) or a Toolbox or Blockset on Linux. When running functions or simulating Simulink models, I receive one of the following errors about a missing MEX file:

 S-Function 'sfun_psbdiscc' does not exist

 MATLAB error message:

 Invalid MEX-file

 Unable to load mex file: D:\MATLAB6p5p1\toolbox\powersys\powersys\sfun_psbdiscc.dll.

 The specified module could not be found.

This has been verified as a bug in MATLAB 6.5.1 (R13SP1) in the way that the installer handles certain Linux installations.

Currently, to work around this issue, try one of the following:

1. Try to reinstall MATLAB or the Toolbox or Blockset which is missing files.

2. If you are missing a specific MEX file, try using the WHICH command to find it.

   which -all sfun_psbdiscc

 sfun_psbdiscc not found.

If it is not found, try to find the corresponding ".c" file.

which -all sfun_psbdiscc.c

 D:\MATLAB6p5p1\toolbox\powersys\powersys\sfun_psbdiscc.c

Browse to the path indicated and use the MEX function on the ".c" file to create the missing MEX file.

cd('D:\MATLAB6p5p1\toolbox\powersys\powersys\')

mex sfun_psbdiscc.c
