#include <mlib.h>
mlib_status mlib_VectorNorm_U8_Sat(mlib_d64 *z, const mlib_u8 *x,
mlib_s32 n);
mlib_status mlib_VectorNorm_S8_Sat(mlib_d64 *z, const mlib_s8 *x,
mlib_s32 n);
mlib_status mlib_VectorNorm_S16_Sat(mlib_d64 *z, const mlib_s16 *x,
mlib_s32 n);
mlib_status mlib_VectorNorm_S32_Sat(mlib_d64 *z, const mlib_s32 *x,
mlib_s32 n);
DESCRIPTION
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
PARAMETERS
Each of the functions takes the following arguments:
z Pointer to the norm of the vector.
x Pointer to the first element of the source vector.
n Number of elements in the vectors.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
returns MLIB_FAILURE.
