                  Subject: Matlab/WinNT Using Wrong Perl
             Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

I'm running Matlab 5.3.1 on WinNT.  I have not checked whether
similar problems occur on Unix versions of Matlab.

Shells started under Matlab have their path environment variable
prefixed with the matlab\bin directory.  This happens regardless
of whether the shortcut starting Matlab specifies the matlab\bin
directory as the start-in/working directory.

This means that statements like
!perl -e "..."
use Matlab's perl, not the version on the system path.

This is not acceptable, since I need to use modules not included
with Matlab's perl.

Of course, I can specify the path to the perl I want to use, but
that's not portable; it requires perl to be installed in the
same location on all machines or additional kludgery.

So, I'd like to do one of the following, but I'm not sure what
the side effects might be:

(1) Delete Matlab's perl and have it use the version installed
    on the system when it needs it for whatever it does with it.

(2) Get Matlab to use the unmodified system path in ! shells so
    that the proper perl is used.

Related to (1), does Matlab use perl for anything besides the
MEX creation script?

Has anyone attempted (1) or (2)?
