When I started thinking about a post featuring CCC, I decided to search online for it - so many different meanings! Here's a small sample:... read more >>

Sometimes people state that they like using MATLAB because it's easy to express their mathematical thoughts. Sometimes there's a follow-on that they then switch to another language for performance. While early in the history of MATLAB, that was sometimes beneficial, it is not so obvious these days. Let's take the example of implicit expansion (also here).... read more >>

Over a long number of years, people have asked whether it's better to use cellfun or a for-loop to perform certain computations. As with so many things in life, the correct answer here is "it depends". Let me give you a bit more insight so you can make good choices.... read more >>

With pleasure, I introduce today's guest blogger, my colleague, Steve Eddins. He has been heavily involved in image processing capabilities in our tools and more recently has also contributed substantially to designing additions and improvements to the MATLAB language.... read more >>

Ever wish you could easily perform some statistical calculations with a sliding window, but find convolution and filtering a bit daunting for this application? Then a set of new functions in Release R2016a might just be for you! ... read more >>

I just got asked a question about a good way to find the closest value in a vector that was less than a threshold. My solution is fairly short, and demonstrates some of my favorite MATLAB techniques. I will compare also show you an "obvious" solution.... read more >>

Today I'd like to introduce guest blogger Matt Tearle who works on our MATLAB Product Training materials here at MathWorks. Matt is on a mission to teach the world MATLAB, but this winter is testing his resolve. Annoyed that 22" of snow forced him to reschedule a training, today he... read more >>

Conventional wisdom for programming MATLAB used to be that using for loops automatically forced a program to suffer from poor performance. Since MATLAB R13 (version 6.5), MATLAB has taken advantage of some innovations that accelerate many for loops so the code has... read more >>

I've fielded some questions recently about how to coordinate multiple arrays changing simultaneously. One example is removing elements for two arrays in the case where either array holds a zero for the location. This is a good opportunity to reiterate ... read more >>

MATLAB has had empty arrays since before I started using the program. When I started, the only size empty array was 0x0. When version 5 was released, empty arrays came along for the N-dimensional ride and got more shapely. ... read more >>
