#include <mlib.h>
mlib_status mlib_VectorMag_U8C(mlib_d64 *m, const mlib_u8 *x, mlib_s32 n);
mlib_status mlib_VectorMag_S8C(mlib_d64 *m, const mlib_s8 *x, mlib_s32 n);
mlib_status mlib_VectorMag_S16C(mlib_d64 *m, const mlib_s16 *x, mlib_s32 n);
mlib_status mlib_VectorMag_S32C(mlib_d64 *m, const mlib_s32 *x, mlib_s32 n);
DESCRIPTION
Each of these functions computes the magnitude vector of the complex input vector.
The following equation is used:
m[i] = (x[2*i]**2 + x[2*i + 1]**2)**0.5
where i = 0, 1, ..., (n - 1).
PARAMETERS
Each of the functions takes the following arguments:
m Pointer to the destination magnitude vector.
x Pointer to the source vector
n Number of elements in the vector.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
