如何在mex文件（MATLAB）中调用imresize

imresize

   #include \"mex.h\"

  void mexFunction(int nlhs, mxArray *plhs[], int nrhs, mxArray *prhs[])
  {
mxArray *output[1];
mxArray *input[3];

input[0] = prhs[0];
input[1] = mxCreateDoubleMatrix(1, 1, mxCOMPLEX);
double *x = mxGetPr(input[1]);
x[0] = 0.5;

//double *p = mxGetPr(input[1]);
//mexPrintf(\"%f\\n\", p[0]);
input[2] = mxCreateString(\"bilinear\");



mexCallMATLAB(0, NULL, 1, &prhs[0], \"imshow\");
mexCallMATLAB(1, output, 3, input, \"imresize\");
mexCallMATLAB(0, NULL, 1, &output[0], \"imshow\");    
    }

Function IMRESIZE expected its second input, SCALE, to be nonzero.
