The function apsa(N,L,plot_flag) implements the Affine Projection Sign Algorithm (APSA) for N iterations to identify a system with L inputs in a set (or L characteristic parameters). It plots the Outputs for comparison and also the Learning Curve if plot_flag=1. The function outputs the min number of iterations taken by the algorithm to identify the system.

For Example:
inp=wavread('BlueFunk-bass1.wav');
inp=inp-(min(inp)); % required for audio signals
h=[1 -4 6 -5 2]; % Known System parameters for a low Pass filter h
Iter=apsa(inp,h,100,5,1);
