There are lots of ways to get help on MATLAB related issues, you can call tech support, e-mail them, or go to the web. This week’s entry is a bunch of links to put in your… read more >>

Add horizontal and vertical lines

Posted by Doug Hull,

How many times have you done something like this?
% BEGIN draw a horizontal line
xMin = 0; xMax = 10; % the current extents of the x axis
yVal = 12;
hold on
plot([xMin xMax], [yVal, yVal])
hold off
% END draw a horizontal line
Hline and Vline are simple but useful tools that draw a horizontal… read more >>

Octave analysis

Posted by Michelle Hirsch,

Christophe Couvreur’s Octave Toolbox has been a favorite of mine since the good old days of FTP file swapping. I’m an acoustician by trade and training, so I’ve often needed to perform octave and third-octave frequency analysis of my time series data. Octave analysis provides frequency content of… read more >>

Consistency in coding

Posted by Doug Hull,

When we first started this project, Scott and I wanted to avoid using the more popular files as our weekly pick. I am going to break from that rule, because in face-to-face interaction I recommend this file to more customers than any other and think it needs to used… read more >>

Search Google® from MATLAB®

Posted by Michelle Hirsch,

Matthew Simoneau’s Google Toolbox has to be one of the coolest MATLAB utilities I’ve ever seen. Google and MATLAB are my most essential computing tools, but I always hate to leave MATLAB in order to Google something. I have yet to do anything tremendously useful with this (other… read more >>

Karen Gondoly's easy-to-use Simulink Alignment Tool lets you align, distribute, and match the size and color of blocks in... read more >>

Find spikes in data

Posted by Doug Hull,

FPEAK finds the peak values in a data set. This is customizable in that you can change the sensitivity of the peak finder and the X and Y range in which to seek peaks. This is a great little utility, the documentation is somewhat lacking, but there are… read more >>

Nancy – a MATLAB humanoid

Posted by Michelle Hirsch,

As Application Engineers, Doug and I have met literally thousands of MATLAB users. We aren’t ones to stereotype, but we’ve noticed a slight trend towards our audiences being predominantly (about 98%) male. One place to find a woman associated with MATLAB is on the File Exchange, though. Walterio Mayol-Cuevas has… read more >>

Shift individual rows and columns

Posted by Doug Hull,

SHIFTD and its three brothers allow you to shift one column or row relative to the others in a matrix. This is one of those functions you will not need very often, but you will be glad not to have to write it yourself when you do need it.

Interactive volume visualization tool

Posted by Michelle Hirsch,

SLICEOMATIC is an interactive tool for displaying cross-sections through three-dimensional data sets. It will also display isosurfaces, which are surfaces within a volume that have the same value. I find it much quicker and easier to use than SLICE for interactive data exploration. You have to try this… read more >>
