Noise Canceling Adaptive Filter

Noise canceling adaptive that uses 2 reference signals instead of 1

Description

This function was written to allow the user to use two reference signals instead of just one to do noise canceling adaptive filtering. Using this function it would be easy to expand it out to more than 2 reference signals if desired.

I take no claim to the theory, just to the Matlab Implementation.

This function works well, though it's a little slow. I suggest replacing the first 9 lines in the for loop with the following:
    r_v(:)=[rv(z); r_v(1:M-1)];
    r_h(:)=[rh(z); r_h(1:M-1)];
and using the initialization
    r_v=zeros(M,1);
    r_h=zeros(M,1);
just before the for loop. This modification has the exact same effect, but is a lot faster. Thanks again for this implementation.
