I have created a dll of a fortran routine. When I try to use the
corresponding mex function in Matlab I obtain the following error:
"error during write, unit -1"
and Matlab is closed.
Can anybody help me?
Thank you,
Grard Goffaux

It think that you either write the the screen or did not
open the file prior to reading. In the past I had to open
a file for unit 6 and add additional code to open a window.
Then we used the Visual Fortran Compiler.

In older versions of MATLAB (version 5 I believe) we did not run in
to problems since the output channel was available.

The program should work when you open a unit and write to
it.

P.S. I could look up the code if you are stuck.
