Simultaneous Iterative Reconstruction Technique

Invert the forward matrix using Simultaneous Iterative Reconstruction Technique (SIRT). Regularization is provided by truncated the reconstruction after a user-supplied number of iterations.

Function Summary

Syntax:	X = art(A, Y, X0, nIter, W);
Inputs:	A	Forward matrix
	Y	The residue appropriate to A
	X0	Initial guess or empty matrix [] for zeros
	nIter	Number of iterations to calculate
	W	Relaxation parameter. Optional: 1.0 if not specified
Outputs:	X	The reconstructed image
