The filter I designed is:

[N, Wn]=buttord(2, 4.83, -3, -15, 's');
[b,a]=butter(N,Wn,'s');
[num,den]=bilinear...

As I have repeatedly posted in recent years, Matlab is advancing towards web-based GUI. The basic underlying technology is more-or-less stable: an

We can use a built-in Matlab popup-panel widget control to display lightweight popups that are attached to a figure window.

Brett's Pick this week is Pottslab - Multilabel segmentation of vectorial data, by Martin.Segmenting images and clustering data are very common challenges, for which MATLAB (and MathWorks Toolboxes) provide numerous solutions. Martin's Potts-energy-based…

By Nick Higham and Alan Edelman (MIT) In a 2005 talk the second author noted that the MATLAB det function returns an odd integer for a certain 27-by-27 matrix composed of $latex 1$s and $latex -1$s…
