[PD] execute matlab using [shell] object

[Gerda Strobl]

Dear all,

I'd like to execute a matlab file using the shell object.
The standard command I use ist
/usr/local/matlab7/bin/./matlab -nodisplay -nosplah.

Sending such a message to the shell object - I only get the info that 
the program starts on the pd-shell:
STDOUT: < M A T L A B >
STDOUT: Copyright 1984-2004 The MathWorks
STDOUT: Inc.
STDOUT: Version 7.0.0.19901 (R14)
STDOUT: May 6
STDOUT: 2004
STDOUT: Warning: Duplicate directory name: /home/gerda/matlab.
STDOUT: To get started
STDOUT: type one of these: helpwin
STDOUT: helpdesk
STDOUT: or demo.
STDOUT: For product information
STDOUT: visit www.mathworks.com.
STDOUT: >>
DONE: 0

but there is no chance, to send it more options (change dir, set a 
paramater). So nothing.

Has someone done this already? (I know there is pdoctave, but octave is 
too slow).
Or do iI treat the shell object in a wrong way? Or is it simply not 
possible? (I'd like to recalculate a matrix in matlab and then write a 
*.mtx file  back to my pddirectory, in order to use it  wth the iematrix 
objects).
Or do I give matlab the wrong commands?

Help would be great!
Thanks,
Gerda
