mediaLib Library Functions mlibVectorAngU8C(3MLIB)
NAME
mlibVectorAngU8C, mlibVectorAngS8C, mlibVectorAngS16C,
mlibVectorAngS32C - vector complex phase (angle)
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlibstatus mlibVectorAngU8C(mlibd64 *a,
const mlibu8 *x, mlibs32 n);
mlibstatus mlibVectorAngS8C(mlibd64 *a,
const mlibs8 *x, mlibs32 n);
mlibstatus mlibVectorAngS16C(mlibd64 *a,
const mlibs16 *x, mlibs32 n);
mlibstatus mlibVectorAngS32C(mlibd64 *a,
const mlibs32 *x, mlibs32 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 MLIBSUCES if successful.
Otherwise it returns MLIBFAILURE.
