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... 続きを読む >>

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... 続きを読む >>

What's your mental model for when to use the MATLAB function feval? Until Release 14 (MATLAB 7), feval was the way to evaluate a function handle. By that I mean you might write code something... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

Use dynamic field references, the notation .(), where possible, instead of setfield, getfield, and eval.
History
In MATLAB 6.5 (Release 13), we introduced dynamic field references into MATLAB. What... 続きを読む >>

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,... 続きを読む >>
