Description

Each of these functions performs an in-place multiplication of one vector by another vector.

For real data, the following equation is used:

xz[i] = xz[i] * y[i]

where i = 0, 1, ..., (n - 1).

For complex data, the following equation is used:

tmp         = xz[2*i]
xz[2*i]     = tmp*y[2*i] - xz[2*i + 1]*y[2*i + 1]
xz[2*i + 1] = tmp*y[2*i + 1] + xz[2*i + 1]*y[2*i]

where i = 0, 1, ..., (n - 1).

Parameters

Each of the functions takes the following arguments:

xz

Pointer to the first element of the first source and destination 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.
