Users have needed access to information about the existence of variables, files, etc. in MATLAB for a long time. The function exist allows us to programmatically check for these entities. exist...더 읽어보기 >>

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...더 읽어보기 >>

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...더 읽어보기 >>

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...더 읽어보기 >>

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...더 읽어보기 >>

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...더 읽어보기 >>

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...더 읽어보기 >>

Use dynamic field references, the notation .(), where possible, instead of setfield, getfield, and eval.
