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

usually you use [shell] with a script that does everything by itself and which does not take any arguments.

e.g.

<snip> #!/bin/sh ## run matlab from here and tell it immediately to execute a .m file which reads in the matrix and does whatever it does and write it out to another file ... ## do something with the outfile, so [iemmatrix] can handle it ...

</snip>

then you just run this script via [shell].

the good thing about this is, that you can debug the script separately from the integration into the patch.

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?

i don't know which commands you are giving to matlab.

note however, that you cannot talk to the program started with [shell] once it is running (e.g. via stdin); i guess you are trying to do something like that.
