Re: About the derivation in firls.m

I just realized I made some changes while testing and I forgot to
include them. This is how it looks like in the cos_ints2 part:

if oddN
        cos_ints = sin((0.5:1:M+1)'*w);
        cos_ints2 = [cos((0.5:1:M+1)' * w(i2)) - cos((0.5:1:M+1)' * w(i1))] ./ 
...
                ([0.5:1:M+1]' * (w(i2) - w(i1)));
else
        cos_ints = [w; sin((1:M)' * w)];
        cos_ints2 = [w(i1).^2 - w(i2).^2;
                cos((1:M)' * w(i2)) - cos((1:M)' * w(i1))] ./ ...
                ([2,1:M]' * (w(i2) - w(i1)));
end
