This Program generates a Pseudo-Random Data set of length 127 for transmission, all the data it transmits is derived from this data set.

30 Jul 2013 Circular Convolution This Program Performs circular convolution of two sequences of equal length. Author: Harsha Vardhan Robert

Helpful function.

It would be great if you make it posible to work also with row vectors. I mean if i give the function two rows i want back a row, if i give the function two columns i want back a column.

Regards,
Robert

Okay, I would say that MLINT and tic/toc concur that preallocation is MUCH faster:
%%
A = magic(500);
B = rand(500);

tic
circonv(A,B);
toc
tic
circonvP(A,B); %Added line: H = zeros(size(g));
toc
%{
Elapsed time is 0.405838 seconds.
Elapsed time is 0.037292 seconds.
%}

A = magic(1000);
B = rand(1000);
tic
circonv(A,B);
toc
tic
circonvP(A,B); %Added line: H = zeros(size(g));
toc
%{
Elapsed time is 5.243947 seconds.
Elapsed time is 0.176474 seconds.
$}

And another fact is that warnings given by any software must not be considered seriously, mlint helps us in some cases, but it does not in this case, consider using tic-toc to know more about the performance
