% usage: Y = hiloanlc(X,l,h) 
% Performs a low pass high pass analysis of the columns of X.
% It is assumed that length(h), length(l) <= #rows(X) 

function Y=hiloanlc(X,l,h)
l = l(:); h = h(:); %change to column vectors if necessary
Yl = circconv2(X,l);
Yh = circconv2(X,h);
Y =[downc(Yl);downc(Yh)];
