Description

Each of these functions computes an in-place multiplication of a vector by a scalar.

For real data, the following equation is used:

xz[i] = xz[i] * c[0]

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

For complex data, the following equation is used:

tmp         = xz[2*i]
xz[2*i]     = tmp*c[0] - xz[2*i + 1]*c[1]
xz[2*i + 1] = tmp*c[1] + xz[2*i + 1]*c[0]

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

Parameters

Each of the functions takes the following arguments:

xz

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

c

Pointer to the source scalar. When the function is used with complex data types, c[0] contains the real part of the scalar, and c[1] contains the imaginary part of the scalar.

n

Number of elements in the vectors.

Return Values

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