plot.cmat: Plot a complex matrix

In mlpeck/zernike: Zernike Polynomials

Plot a complex matrix

Description

Plot a real valued function of a complex matrix

Usage

plot.cmat(X, fn = "Mod", col = grey256, 
	cp=NULL, zoom=1, gamma=1, ...)

Arguments

X	A complex valued matrix
fn	A function returning a real value
col	Color palette for graph
cp	pupil parameters as returned by pupil.pars
zoom	zoom factor for display
gamma	gamma value for display
...	Other parameters to pass to image.default

Details

In addition to the functions described in complex fn can be assigned the values "logMod", which will call an internally defined function returning the value log(1+Mod(X)), "Mod2" to plot the power spectrum, and "logMod2" to plot the logarithm of the power spectrum.

If the parameter cp is passed axes will display spatial frequencies in cycles per pupil radius.

Value

none

Note

This is used primarily for displaying FFT's of interferograms. In the case of an interferogram in which the background has not been removed use fn="logMod" to make the first order sidelobes visible.
