Как использовать coder.ceval для конвертации Matlab в C ++?

/ 15 мая 2019

У меня есть код Matlab, который я хочу преобразовать в C ++. Он использует предоставленный Matlab файл примера mexfunction.c: 

#include "mex.h"

void
mexFunction(int nlhs,mxArray *plhs[],int nrhs,const mxArray *prhs[])
{
    int        i;

    /* Examine input (right-hand-side) arguments. */
    mexPrintf("\nThere are %d right-hand-side argument(s).", nrhs);
    for (i=0; i<nrhs; i++)  {
        mexPrintf("\n\tInput Arg %i is of type:\t%s ",i,mxGetClassName(prhs[i]));
    }

    /* Examine output (left-hand-side) arguments. */
    mexPrintf("\n\nThere are %d left-hand-side argument(s).\n", nlhs);
    if (nlhs > nrhs)
      mexErrMsgIdAndTxt( "MATLAB:mexfunction:inputOutputMismatch",
              "Cannot specify more outputs than inputs.\n");

    for (i=0; i<nlhs; i++)  {
        plhs[i]=mxCreateDoubleMatrix(1,1,mxREAL);
        *mxGetPr(plhs[i])=(double)mxGetNumberOfElements(prhs[i]);
    }
}

Код Matlab exMexFunction.m ниже: 

function exMexFunction


B=[0 1; 0 0; 1 0; 1 1];
C=[1.5 0; 0.5 0; 0.5 1.5; 1.5 1.5];


if coder.target('MATLAB')
    res=B+C;
    res1=sum(sum(res));
    disp(['sum: ',num2str(res1)])
else

    coder.updateBuildInfo('addSourceFiles','mexfunction.c');

    P0=0;
    P0=coder.ceval('mexFunction', B,C);

end
