Description

Each of these functions splits a complex vector into separate vectors containing the real and imaginary parts.

The following equation is used:

r[k] = z[2*k]
i[k] = z[2*k + 1]

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

Parameters

Each of the functions takes the following arguments:

r

Pointer to the first element of the real part.

i

Pointer to the first element of the imaginary part.

x

Pointer to the first complex element of the source vector. x[2*k] contains the real part, and x[2*k + 1] contains the imaginary part.

n

Number of elements in the vectors.

Return Values

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
