Making maps in MATLAB

Posted by Doug Hull,

MATLAB has a lot of good examples in the documentation, but you can never have enough of them. A healthy amount of my job is to produce custom demos for potential customers. When I can, I do these before the meeting, but sometimes they ask you for something... read more >>

Live video in MATLAB

Posted by Michelle Hirsch,

With the Image Acquisition Toolbox, it is now possible to stream live video into MATLAB, using devices ranging such as a web cam, FireWire video camera, or analog camera hooked up to a framegrabber. The Toolbox comes with a nice preview window that lets you set up your scene, but... read more >>

Quick directory navigation

Posted by Michelle Hirsch,

OK, I'm breaking the number one rule that Doug and I set up for our submissions - I'm picking my own file. Hey, it's my forum, so I guess I can do what I want! I have been using a couple of really small directory utilities I wrote so much... read more >>

Making a splash

Posted by Doug Hull,

People have been making full-fledged applications in MATLAB for quite a while, and that is becoming even easier because the MATLAB compiler now works for the entire MATLAB language. A big application just crys out for a splash screen to give it that little bit of polish. So find… read more >>

Volume visualization

Posted by Doug Hull,

Sliceomatic was an early pick here at pick of the week. Here is another tool, Orthogonalslicer, that does a similar job, but in a different way. This tool lets you look at the slices orthogonally rather than in isometric view. One thing beyond the great functionality of this tool is that... read more >>

Using Java in MATLAB

Posted by Doug Hull,

This week’s pick by Michael Kleder uses Java to determine if a number is prime. I liked this because it quietly makes use of Java. I rarely get a chance to program in Java, so when I saw this I took note of it as somewhere to start… read more >>

Smooth animations in MATLAB

Posted by Doug Hull,

This is a great animated clock made in MATLAB, and I chose it for several reasons:
1) Tim made use of some new R14 language features like nested functions; this makes argument passing easier to do among sub-functions.
2) The code is well commented.
3) I plan to modify this as a countdown… read more >>

Export to PowerPoint

Posted by Michelle Hirsch,

At a MathWorks conference Doug and I attended last week, there was a lot of talk about SAVEPPT – Mark Brown’s submission that automatically creates PowerPoint documents from MATLAB figures and Simulink windows. SAVEPPT is a really simple, easy to use utility that makes decent looking PowerPoint slides with… read more >>

UNPLOT

Posted by Michelle Hirsch,

I just became a huge fan of Tobin Driscoll, for his submission of UNPLOT to MATLAB Central. And I swear it has nothing to do with the fact that he goes to the University of Delaware, where I did my Ph.D. (go Blue Hens!)
Like most MATLAB users,… read more >>

Colorbars for filled contours

Posted by Michelle Hirsch,

This weeks pick adds very useful functionality for anybody who works with filled contour plots (as created by contourf). MATLAB's standard colorbar isn't particularly well suited to filled contours, since it displays ever color in the colormap while the filled contour plot uses a smaller subset of colors. Blair Greenan's... read more >>
