Each of these functions computes the vector normal.
The following equation is used:
n-1 z[0] = ( SUM x[i]**2 )**0.5 i=0
Each of the functions takes the following arguments:
Pointer to the norm of the vector.
Pointer to the first element of the source vector.
Number of elements in the vectors.
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
