function [A,B,C,errflag,iter] = swatld (X,A0,B0,F,tol,maxiter);

Description:
Fits a PARAFAC model to a three way array via Self-Weighted Alternating Trilinear Decomposition

Inputs:
X: array
A0,B0: initial estimations for the loading matrices A and B (here random matrices)
F: number of components to extract
tol: convergence criterion based on the relative decrease in fit
maxiter: maximum number of iterations.F: Insert description
 

Outputs:
A,B,C: loading matrices
errflag: indicates normal exit (0) or maximum number of iterations (1)
iter: number of iterations
