MATLAB: License for private toolbox

licensingMATLABmex api

I am a software developer who has developed a private toolbox. Is there anyway I can have some kind of license control on the toolbox to prevent a customer from unrestricted distributing the toolbox.

Possible approaches: Piggy-back on the matlab license manager? A mxLicense( ) function to let me check the license number from C code?

Best Answer

The license number can be check easily by using the license command in mexCallMATLAB. But this can be replaced easily by a user-defined function, such that this does not have a severe security level.

You find many discussions here and some contributions in the FileExchange for creating a unique machine ID. And internet search engine might be more efficient than the forum search.

Your main problem is that you need to create the output array PLHS(1) before you access it. Also your NLHS and NRHS types are wrong. Try this:

#include <fintrf.h>
C
C Gateway routine
C
    SUBROUTINE MEXFUNCTION(NLHS, PLHS, NRHS, PRHS)
    implicit none
C mexFunction arguments:
    MWPOINTER PLHS(*), PRHS(*)
    INTEGER NLHS, NRHS
    mwPointer, external :: mxGetPr, mxGetPi
    mwPointer, external :: mxCreateDoubleMatrix, mxCreateNumericArray
    mwSize, external :: mxGetM, mxGetN
    MWPOINTER YPP 
    mwSize M, N
    integer*4 ComplexFlag
    REAL *8 RYPP(1)
    RYPP(1) = 10
    M = 1
    N = 1
    ComplexFlag = 0
    PLHS(1) = mxCreateDoubleMatrix( M, N, ComplexFlag )
    YPP = MXGETPR(PLHS(1))
    CALL MXCOPYREAL8TOPTR(RYPP, YPP, M*N)
    RETURN
    END
