Hi,
I'm trying to run the following piece of code:
void mexFunction(
int nlhs,
mxArray *[],
int nrhs,
const mxArray *prhs[]
)
{


using namespace libbase;


vector <double> y;



double *xValues;

int i,j;



mxArray *value;





xValues = mxGetPr(prhs[0]);

int rowLen = mxGetN(prhs[0]);
int colLen = mxGetM(prhs[0]);


y.init(2);
y=0;

y(1)=3;
y(2)=3;



printf("the rowlength is=%d",rowLen);

value = mxDuplicateArray(prhs[0]);





double neigh[] = {3,3};
double *pr;
mxArray *p;




int nlhs1, nrhs1;
mxArray *plhs1[2], *prhs1[2];


nlhs1 = 2;
nrhs1 = 2;
prhs1[0]=value;


prhs1[1] = mxCreateCellMatrix(2, 1);
pr = mxGetPr(prhs1[1]);
for( i=0; i<=1; i++ ) {
pr[i] = neigh[i];
}

mxSetCell(*p,1, );
mexCallMATLAB(nlhs1,plhs1,nrhs1,prhs1,"wiener2");


return;

}

i first run the following:
a = im2double(imread('stego.tif'))'

Then i compile my mex file.
And I recieve the following output with this error:
the rowlength is=256the value of neigh is=0.000000the value of neigh is=3.000000??? Error using ==> ones
Size vector must be a row vector with real elements.

Error in ==> wiener2 at 55
localMean = filter2(ones(nhood), g) / prod(nhood);


Can anybody help me in this regard?
