17 Nov 2010 On Off Keying This is Basic ASK Modulation Author: Harsha Vardhan

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

This file has some inherent mlint error, it does not run

15 Nov 2010 Circular Convolution This Program Performs circular convolution of two sequences of equal length. Author: Harsha Vardhan Sean de

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.
$}

02 Nov 2010 Circular Convolution This Program Performs circular convolution of two sequences of equal length. Author: Harsha Vardhan Vardhan, Harsha

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

Preallocating does not have a very great advantage in this case. The speed is nearly same. This is a very easy algorithm which I've embedded in many of my codes
