Allows one to replace the GPU array in a dense matrix with an array provided by the user. This is useful to avoid copying an array into a matrix

You can return to the original array with a call to <A HREF="../Mat/MatDenseCUDAResetArray.html#MatDenseCUDAResetArray">MatDenseCUDAResetArray</A>(). The user is responsible for freeing this array; it will not be
freed when the matrix is destroyed. The array must have been allocated with cudaMalloc().
