Filter Design Using SPTool's Pole/Zero Editor

by Paul Pacheco and Anne Mascarin

This article explores using the Signal Processing Toolbox's Pole/Zero Editor to design and compare FIR (Finite Impulse Response) and IIR (Infinite Impulse Response) comb filters. We will show that adding poles to an FIR comb filter improves the frequency response by reducing the bandwidth of the notch. Further improvements can be achieved by moving the poles closer to the unit circle. read more

Tips for Making a Stand-Alone Application from Your MATLAB Graphical Application

by Peter Fry

With the recent release of the MATLAB C/C++ Graphics Library, porting your MATLAB code to a completely stand-alone application becomes much easier. With many MATLAB applications, one call to the MATLAB Compiler will create a fully functioning application. There are limitations that may be encountered however, and this article contains tips to help overcome them. read more

MATLAB Programming Contest Analysis

Our analysis of the Surveyor contest is in two parts:

"Strategies, Randomizations, and Optimizations"
First, we take you line by line through the winning entry, with an analysis of the algorithms, strategies, and optimizations in the final winner, NoSoup4U!1.

"In Praise of Tweaking"
Next we take a quantitative look at how these innovations developed over the course of the contest. In this analysis, we look at the interplay between radical innovations and tweaking battles in the development of the winning entry.
For both articles: read more
