%  RectPolar_2_Cart: cartesian to rectopolar conversion
% 	C = RectPolar_2_Cart(X[,dens,maxiter,lambda])
%  Inputs
% 	X		possibly complex n*n array of rectopolar samples
% 			of a trigonometric polynomial of degree n
% 	dens	boolean. dens=1: density normalization
% 			dens=0, no density normalization. Default 1.
% 	maxiter	maximum number of iterations: default 20.
% 	lambda	relaxation factor: default .9
%  Outputs
% 	C		possibly complex n*2n array of cartesian samples 
%  Description
% 	The samples of the array C are used in scan-line fashion
% 	and exact trigonometric interpolation to obtain the
% 	samples of the array X on a rectopolar system.
