Re: passing and modifying structures in mex octave functions

[hafedh trigui]

Thank you very much Ben. I have indeed looked at this example as well as the matlab example phonebook.c where it is possible to read a structure and re-write it in another form or change its type to cell...

In my example, I'd like to pass a structure array to other C++ function and my problem is that other than mexFunction, the other functions do not recognize the same variable as a Structure array.

I'll greatly appreciate your help or Arnaud help or anyone else from Octave communauty.

Thanks again

Hafedh

I'm not familiar with this subject, but I noticed there is a section in the manual on this subject. An example is included.

    http://www.gnu.org/software/octave/doc/interpreter/Structures-with-Mex_002dFiles.html

My c/c++ experience is very limited (close to nil). I expect you'll be able to solve your problem faster than I can, but if the link above doesn't help, I can give it a try.
