function [y,ny] = conv_m(x,nx,h,nh)
% Modified convolution routine for signal processing
% ---------------------------------
% [y,ny] = conv_m(x,nx,h,nh)
%  y = convolution result
% ny = support of y
%  x = first signal on support nx
% nx = support of x
%  h = second signal on support nh
% nh = support of h

nyb = nx(1)+nh(1); nye = nx(length(x)) + nh(length(h));
ny = [nyb:nye];
y = conv(x,h);
