Description

Each of these functions computes the complex vector from two vectors representing the real and imaginary parts.

The following equation is used:

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

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

Parameters

Each of the functions takes the following arguments:

z

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

r

Pointer to the first element of the real part.

i

Pointer to the first element of 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.
