Inverting Logic in an Algorithm 7

Posted by Loren Shure,

A while ago, a colleague needed to use the sinc function to interpolate some channel data posted by the IEEE 802.15.3a working group. The files they supplied were large and the interpolation took a while. Seems like a job worthy inspecting the code and using the profiler (see references... read more >>

More on eval 2

Posted by Loren Shure,

I recently wrote an article on Evading eval. A couple of users asked me how to avoid using eval in the case post under Code Clarity / Readability. The answer is you can't, unless you rethink the code altogether. ... read more >>

Evading eval 5

Posted by Loren Shure,

If you are a regular reader of the MATLAB Usenet newsgroup, comp.soft-sys.matlab, found on the MathWorks User Community page, you are probably familiar with repeated advice to not use the MATLAB function eval . Today I plan to tell you more about why this is generally good advice.... read more >>

Sort of Find a Solution

Posted by Loren Shure,

In MATLAB 7, Release 14, we enhanced two useful and often used functions, sort and find in part because we noticed some common coding patterns in our MATLAB code and customers'. With the older patterns we found, we felt we could create new options in these functions that... read more >>

Introduction 8

Posted by Loren Shure,

One of my favorite things about MATLAB is that I can write a mathematical algorithm using the same notation appearing in a technical book or paper. For algorithms that are naturally matrix-based, the economy and clarity of the MATLAB code contribute to the program's elegance.... read more >>
