Re: Seeking help in Octave C++ API

Hi Carnë,
Thanks for your response. I want to make use of the octave function and I
want to call it from my C++ code. I know my code will then depend upon
octave libraries but it doesn't matter. I recently went through the link "
https://octave.sourceforge.io/coda/c58.html" and I saw the example of C++
code  of matpow function. In the same way I want to call imregionalmax
function. But I found out that this function is a part of image package of
octave. So I downloaded image-2.12.0 and inside that folder I found out a
c++ file *imreconstruct.cc* & *imreconstruct* function is used in the
implementation of imregionalmax in octave. So, now, if I can call
*imreconstruct* like *matpow* function in c++ code (using octave library)
then I can also build imregionalmax function.
So, please help me in calling the *imreconstruct* function from C++ code
using octave API or *imregionalmax* function directly. It will be very
helpful for me if you provide a demo C++ code.
Thanking you.
Your response will be highly appreciated.
