U hav missed the defn of variable r.
19 Jul 2012 Envelope Detction for Signal Analysis Computes the envelope of the signal by two methods: 1.LPF method 2.Hilbert Transform Author: Santhana Raj

@Jan Simon

True, This is just a demonstration of the two methods. Who would want to use different methods when one's ultimate aim is to do some envelope detection.

I thought it would be easier, as any one can compare the methods for their application and use the code from the program by coping those set of lines and reusing them in their main code.

04 Jul 2012 Poisson Image Editing This is an implementation of the Poisson Image Editing. Author: Masayuki Tanaka

When I Run the demo.m, I get an error sayin that unable to find girl.png

can anyone help me regarding this??
03 Jul 2012 Find angles Find angles of triangle and/or quadrilateral when vertices are given. Author: Siva Srinivas Kolukula

good work & a simple way to find, rather than the Heron's formula which is both tedious and problematic when the vertices are closer.

good work
Cheers

Wonder why the author didnt use Waveden function inbuilt in matlab?
