If by create you mean typecasting, then no. If by create you mean populate then yes:

 mwSize m = 100, n = 10; //Array size
 double * yourData = new double[m*n]; //Need to populate with the data you want
 mxArray *pa = mxCreateDoubleMatrix(m, n , mxREAL)
 double *startPa = mxGetPr(pa);
 //In C
 memcpy ( startPa, yourData, m*n*sizeof(double) ); 
 //Alternatively
 copy ( pa, pa+(m*n), yourData );
 delete yourData;
