Accessing handle graphics from within Fortran mexfunction

2 views (last 30 days)
Can you access Matlab's handle graphics from within a Fortran mexFunction? I see that there are mexSet and mexGet functions; however, they appear to apply only for C mexFunctions.
Thanks a million, Bill

Hi Otis,
I guess (!) the answer is yes. Handles itself are just usual doubles. Therefore you should be able to call the set and get by something like
mxArray* pprhs[3];
pprhs[0] = prhs[0]; // assuming prhs[0] is the handle
pprhs[1] = mxCreateString("tag");
pprhs[2] = mxCreateString("Bill");
mexCallMATLAB(0, plhs, 3, pprhs, "set");

@Titus: Please fix the prhs->pprhs confusion in your code. The line "prhs[0] = mxDuplicateArray(prhs[0])" will blow-up the memory manager...

You can get Fortran versions of mexGet and mexSet in my Fortran 95 interface package, which can be found here:
They work the same as their C counterparts. You can also find a lot of other useful functions & utilities in this package, many of which are not available in the C API.
