Hello,

 

 

I want to program octave statement in c++. The first simple example is B=fft2(A). The problem in c++ file return variable B( ComplexMatrix)

 

Where to put B

 

a) in octave_value_list args or in statement

 

b) B = do_fft2(args,"fft2",0 );

 

 

In both cases I get compiler errors.

 

Please help.

 

Sincerely

 

Hans

Hello Hans,

I assume you want to use Octave as a library for building a standalone program calling the fft2 function in it, without starting Octave itself. A good starting point for this case is this section of the manual (and the surrounding ones):

https://www.gnu.org/software/octave/doc/interpreter/Standalone-Programs.html#Standalone-Programs

According to this I modified your program (see attachment). It compiles and runs on my machine (Ubuntu 13.04, Octave 3.7.6+) with:

mkoctfile --link-stand-alone standalone.cc -o standalone

I don't understand, why you copied many Octave functions from the source in it, especially the DEFUN_DLD macros are usually for OCT-files, you can run from Octave itself, what I assume you don't want to do.

HTH,

Kai
