#include
mlib_status mlib_VectorAng_U8C(mlib_d64 *a,
const mlib_u8 *x, mlib_s32 n);
mlib_status mlib_VectorAng_S8C(mlib_d64 *a,
const mlib_s8 *x, mlib_s32 n);
mlib_status mlib_VectorAng_S16C(mlib_d64 *a,
const mlib_s16 *x, mlib_s32 n);
mlib_status mlib_VectorAng_S32C(mlib_d64 *a,
const mlib_s32 *x, mlib_s32 n);
DESCRIPTION
Each of these functions computes the phase vector of a com-
plex vector. The following equation is used: a[i] = atan(x[2*i + 1] / x[2*i])where i = 0, 1, ..., (n - 1).
PARAMETERS
Each of the functions takes the following arguments: a Pointer to the destination phase 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.
