Circular Harmonics

The action of this operation is to either create a circular harmonic as shown above or to extract is as shown bellow. The function above is a complex one with a real and imaginary parts. The magnitude is one.

If the "Extract" radio button is selected and the image at the left is in the big array, that on the right will be the result.

The "Radial weight" switch is in the window so that you can choose to weight the contribution of a point with the radius at which it is placed. The affect is so that if a line of values is placed from the center out along a radius, these values will be carried around in a disk pattern.
