NAME
mlib_VectorDistance_U8_Sat, mlib_VectorDistance_S8_Sat, mlib_VectorDistance_S16_Sat, mlib_VectorDistance_S32_Sat - vector Euclidean dis- tance SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VectorDistance_U8_Sat(mlib_d64 *z, const mlib_u8 *x, const mlib_u8 *y, mlib_s32 n); mlib_status mlib_VectorDistance_S8_Sat(mlib_d64 *z, const mlib_s8 *x, const mlib_s8 *y, mlib_s32 n); mlib_status mlib_VectorDistance_S16_Sat(mlib_d64 *z, const mlib_s16 *x, const mlib_s16 *y, mlib_s32 n); mlib_status mlib_VectorDistance_S32_Sat(mlib_d64 *z, const mlib_s32 *x, const mlib_s32 *y, mlib_s32 n); DESCRIPTION
Each of these functions computes the Euclidean distances between two vectors. The following equation is used: n-1 z[0] = { SUM (x[i] - y[i])**2 }**0.5 i=0 PARAMETERS
Each of the functions takes the following arguments: z Pointer to the distance between the two vectors. x Pointer to the first element of the first source vector. y Pointer to the first element of the second 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. ATTRIBUTES

Each of these functions computes the dot product of two vectors, defined by the following equation: Z = X . Y* where Y* is the conjugate of the Y vector. For real data, the following equation is used: n-1 z[0] = SUM (x[i]*y[i]) i=0 For complex data, the following equation is used: n-1 z[0] = SUM (x[2*i]*y[2*i] + x[2*i + 1]*y[2*i + 1]) i=0 n-1 z[1] = SUM (x[2*i + 1]*y[2*i] - x[2*i]*y[2*i + 1]) i=0 PARAMETERS
Each of the functions takes the following arguments: z Pointer to the dot product of the two vectors. x Pointer to the first element of the first source vector. y Pointer to the first element of the second 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. ATTRIBUTES
