I want to assign to plhs[0] a scalar of type uint64_t.
Not sure what function to call.
e.g. if I have
uint64_t y=123;
and I want to return y to Matlab
I tried
plhs[0] = mxCreateDoubleScalar(y);
But this is not the right call as it is not a double. How to create a uint64_t variable in the mex function? in there another mxCreate...

mxArray *A;
A = mxCreateNumericMatrix(1, 1, mxUINT64_CLASS, mxREAL);
*(mxGetUint64s(A)) = 123;
