Description

Each of these functions performs an in-place multiplication of a scalar to a matrix.

For real data, the following equation is used:

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

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

For complex data, the following equation is used:

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

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

Parameters

Each of the functions takes the following arguments:

xz

Pointer to the source and destination matrix.

c

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

m

Number of rows in each matrix.

n

Number of columns in each matrix.

Return Values

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