Today I’d like to introduce a guest blogger, Sarah Wait Zaranek, who is an application engineer here at The MathWorks. Today she talks about speeding up code from a customer to get... 続きを読む >>

Recently someone at MathWorks asked me how he could automate the renaming of a bunch of M-files containing underscores ('_') in the names with derived names that removed the underscores and used... 続きを読む >>

Do you ever need both the minimum and maximum values on the same data? Sometimes I do, for example, when I want to tweak the limits of a 2-dimensional plot. So... 続きを読む >>

This post continues in the theme of other recent ones, questions frequently posed to me (and probably others). It has to do with initializing structures. There is a healthy... 続きを読む >>

This post continues in the theme from my last post, where people routinely come to me on a topic. Today I want to distinguish
between indexed assignment, where you can take advantage of scalar... 続きを読む >>

I have received comments from several savvy customers suggesting that we remove the function inv from MATLAB. The reasons are because people who don't know enough numerical analysis... 続きを読む >>

Recently I mentioned that I would describe a relatively new optimization we have for MATLAB code that allows some function calls to operate on variables without allocating more... 続きを読む >>

I recently was working with Dave Schoppik on extracting a subset of elements from his dataset. In his lab, they work to understand
the ways our brains enable us to move. Here's Dave's description.

I'm pleased to introduce Tim Davis as this week's guest blogger. Tim is a professor at the University of Florida, and is the
author or co-author of many of our sparse matrix functions (lu, chol,... 続きを読む >>

There are some cases, particularly simulations, in which we need to choose a few items from a finite list. A friend mentioned to me that he was doing a Monte Carlo... 続きを読む >>
