DESCRIPTION

Each of these functions multiplies a matrix by a scalar and then adds an offset.

For real data, the following equation is used:

z[i] = a[0]*x[i] + b[0]

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

For complex data, the following equation is used:

z[2*i]     = a[0]*x[2*i] - a[1]*x[2*i + 1] + b[0]
z[2*i + 1] = a[1]*x[2*i] + a[0]*x[2*i + 1] + b[1]

where i = 0, 1, ..., (m*n - 1).  

PARAMETERS

Each of the functions takes the following arguments:

z

Pointer to the destination matrix.

x

Pointer to the source matrix.

a

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

b

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