conv_m.m

DSP with Matlab by Proakis and Ingle

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);
