complexMult --- multiply a complex image with an integer/float image
DESCRIPTION
The complexMult operator serves to perform complex multiplication in the
frequency domain for FFT analysis. The top input port is connected to a
complex image resulting from a forward FFT operation and the bottom input
port is connected to an integer or float image. In the case of an integer
image, for example, the image would represent a mask where 1's retain the
complex image and 0's remove regions. The result is a complex image at the
output port for use in an inverse FFT back to the spatial domain.
