Once and for All16

I was talking to my long-time colleague, Mike Croucher, who joined MathWorks team recently (yay!). About a bunch of interesting topics, some of which could be good fodder for a blog post. Today I... 更多内容 >>

The Meaning of CCC11

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:... 更多内容 >>

Importance of Implicit Expansion For Performance6

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).... 更多内容 >>

Which Way to Compute: cellfun or for-loop?9

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.... 更多内容 >>

MATLAB arithmetic expands in R2016b52

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.... 更多内容 >>

Moving Along6

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! ... 更多内容 >>

Finding the Closest Value Less than a Threshold15

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.... 更多内容 >>

MATLAB Behavior: for34

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... 更多内容 >>

Coordinating Zero Removals from Multiple Arrays13

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... 更多内容 >>
