Hey;

I try to get the following done:

- I have a very large C program, which extracts data from an Oracle data base

- I want to pass some of the data to octave

- use my own octave function on that data

-pass it back to my C routine….

 

I tried to use google and the octave manual. I don’t think that mex files or oct files are the right tools to do that ( I want to call Octave from within a c-file). I have found quite a body of information how MATLAB handles these tasks (http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_external/f15075.html)

 

Can this be done in Octave too? Are there any counterparts in octave to the matlab engPutvariable, engEvalstring and similar functions?

Any hints/links how to handle the problem would be welcome.

Thank you  very much in advance

regards

Octave can be embedded in C++ applications relatively easily. A basic example is in the manual under "Dynamically Linked Functions/Standalone Programs".
Native embedding interfaces are also available, for instance for Python:

another option is to simply launch Octave as an external process and communicate through pipes.
