The usual hack is to encapsulate the pointer in a MATLAB uint64 variable. I.e., set the data area of a uint64 mxArray to the value of your pointer and pass that variable around. However, you need to be careful that the pointer is indeed valid to use in that other mex routine or it will cause a MATLAB crash.
