if i change the phonebook.c example in matlab to phonebook.cpp, i receive an error message.
the error message line is 49.
classid flags = mx calloc(fields, sizeof(mx classid));
it seems that the mxcalloc function can only be used in c.
is there a way to use it in the cpp extension as well?

The "phonebook.c" is composed of lots of C APIs for MATLAB (e.g., mxGetClassID), and you cannot change the extention to cpp to use it on the fly. You can find a cpp version of the "phonebook" example with the command below. Please find how it is different from the C version.
edit([matlabroot '/extern/examples/cpp_mex/phonebook.cpp'])
