Why identifier "mxGetUint64s" is undefined in mex or cudamex?

Hi, I am trying to deal with unsigned long format arrays in mex. I found in mxGetUint64s page that I should use mxGetUint64s instead of mxGetPr or mxGetData. But in the mini-sample script below, I always get the error "identifier "mxGetUint64s" is undefined". I had already include the "matrix.h" header file as below. Could anyone give me some suggestions?
% test.c or test.cu
#include "mex.h"
#include "matrix.h"
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
unsigned long* ptr = mxGetUint64s(prhs[0]);
}
The following error happens with mex and cudamex both.
>>> mex('test.c') % or mex('test.cu')
error: identifier "mxGetUint64s" is undefined
Besides, if I use mxGetData with double format input, it works well as below.
#include "mex.h"
#include "matrix.h"
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
double* key = (double*)mxGetData(prhs[0]);
}

What happens if you build your MEX-file using the interleaved complex API by passing the -R2018a option to the mex command as shown in the API Version section on the documentation page?
