[y,H]=conv_tp(h,x)
function [y,H]=conv_tp(h,x)

% Linear Convolution using Toeplitz Matrix

% ----------------------------------------

% [y,H] = conv_tp(h,x)

% y = output sequence in column vector form

% H = Toeplitz matrix corresponding to sequence h so that y = Hx

% h = Impulse response sequence in column vector form

% x = input sequence in column vector form

%

Nx = length(x); Nh = length(h);

hc=[h; zeros(Nx-1, 1)];

hr=[h(1),zeros(1,Nx-1)];

H=toeplitz(hc,hr);

y=H*x;
