% CONV_MTX Convolution matrix.
% If 'x' is a column vector of length 'nx', then conv_mtx(x,nh) gives a toeplitz
% matrix 'X' of size (nx+nh-1) times (nh). 'nh' is the length of the column vector
% 'h' with which 'x' is convolved. Thus finally 'X*h' is same as conv(x,h).
% If 'x' and 'h' are row vectors, then 'X' is of size (nh) times (nx+nh-1).
% Then 'h*X' is same as conv(x,h). This does not depend on the in built command
% 'TOEPLITZ'.
