In the third video in his series, Matt investigates speeding up his code, starting first by using the profiler to see where most time is spent.

In the next video in his series on reading web pages, Matt uses a try/catch statement to make his code more robust.
if (typeof(playerLoaded) === ‘undefined’) {var playerLoaded = false;}(function… 続きを読む >>
This week, in the first of a series of videos, my colleague Matt Tearle demonstrates how to read web pages with the webread function. In this application, he reads a random Wiki page and follows the… 続きを読む >>
Along with the examples in part one and part two of this series, another method I use to display the status of a long running script is a little utility I made that uses a function handle.

Previously, I showed how you could use fprintf to display status updates of a long running script. Another technique I use is to capture these updates in a uitable, so I can then easily view the… 続きを読む >>
I have a number of scripts that take several hours to run and I like be able to track their progress. I use a few techniques to do this, including this first example, which just uses fprintf…. 続きを読む >>
Recently I have been using MATLAB tables a lot to store large heterogeneous datasets. In many cases, the rows contain information about files in a file system. As I need to access the files… 続きを読む >>
Using MATLAB in recent years on computationally intensive problems that take a long time to run, I notice that MATLAB does not always make use of all the cores on my machine. Also, sometimes I… 続きを読む >>
I have a number of scripts that I have been maintaining for many years. They are not in version control but I still want to make edits and be able to access the code in previous versions. So I use a… 続きを読む >>
In release 2014b there is a new preference that lets you set MATLAB’s initial working folder to be the last folder used in the previous MATLAB session. Here I show when it can be useful and… 続きを読む >>
