Algebraic Reconstruction Technique

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

Function Summary

Syntax:	X = art(A, Y, X0, nIter, W, iMeas);
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
	iMeas	The initial row to project on to. Optional: 1 if not specified
Outputs:	X	The reconstructed image
