[MATRIX-SIG] Get array elements in c?

The data layout of this type is just 16 floats, as for a NumPy array
of Float32. As always, there are several ways to do what you want.
Perhaps the clearest is to cast array->data to Matrix and copy as
if you had two Matrix variables. Or just copy 16 floats linearly.
