Scalar Expansion and More 31

Posted by Loren Shure,

Last week I received email from a blog reader asking about extending the meaning of the arithmetic operators to do more than scalar expansion, and instead extend the expansion to singleton dimensions. In this post, I discuss the evolution of scalar expansion in MATLAB, talk about possible future designs, ... read more >>

Existence in MATLAB 12

Posted by Loren Shure,

exist can be called with one argument (a string) to test if that specific name is known and available in MATLAB in any form. If we program carefully and check the output result of exist, then we can be sure we know whether we are dealing with a MATLAB... read more >>

What’s the Big deal? 15

Posted by Loren Shure,

So, what is the big deal? To start with, this week marks my 19th anniversary at MathWorks. Never would I have guessed back then what I am up to now, including talking about MATLAB with so many customers. I look forward to many more years working with... read more >>

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 >>
