How can I interface with octave with C++?

[posadasarraez]

Hi,

I'm an student and I'm working with Octave. I've the same issue than
this user:

https://www.daniweb.com/programming/software-development/threads/445631/how-can-i-interface-with-octave-with-c

I have a .mat file and I can work with it in Octave without any problem.
I need load that file in a C++ program and
I wonder if is there any example code or something that could help me.

Thanks,
Miguel

Hi Miguel, there is an example in the source tarball:
examples/code/embedd.cc
which shows howto call GNU octave from C++. Keep in mind that you link
against GNU Octave and thus your project needs to be GPL compatible.

If you just want to read a .mat file (and not doing any calculations in
GNU octave) you might have a look at something like

Hi,

If what you need is ti read and write data in octave formats, you may find this class useful :

I write it for myself to simplify this task, it was not intended for distribution but it may be useful as an example...
