11 Jul 2012 Decimate Polygon Simplify a 2D closed, piecewise linear contour by specifying boundary offset tolerance. Author: Anton Semechko

Andrii, just out of curiosity, what would you want to get from: https://maps.google.co.uk/maps?q=guggenheim+museum+bilbao&hl=en&ll=43.268728,-2.933803&spn=0.001457,0.002902&sll=43.267445,-2.937035&sspn=0.002914,0.005804&t=h&hq=guggenheim+museum+bilbao&z=19
31 Jan 2012 UIMAGE - UIMAGESC Display image with non-linearly spaced axis. Author: Frederic Moisy

Just a question: What improved features does this provide compared to simply calling:

pcolor(x,y,c),shading flat,axis ij

28 Jul 2011 contourz 3D contour plot on a surface. Author: M MA

Works and follows a gap in Mathworks contour functions. Much apreciated!
03 Jun 2011 Loader of a .txt file to a MATLAB matrix Loads a content of a .txt file and stores it in a MATLAB matrix Author: Luka

Luka, twice you've said "one is able to add a bit customized functionality" - it would be more informative if you gave some example of what extra functionality you provide.
29 Jun 2010 Lee filter Lee filter for reducing speckle noise in images Author: Grzegorz Mianowski

In the image processing toolbox there is a mathworks supplied function wiener2.m that implements the Lee filter. Since a requirement for using this function is the image processing toolbox I fail to see any utility of this function, when one would already have the image processing toolbox with the Lee-filter if one can run this function. Further that function for example lets me choose the size of the neighbourhood to use for filtering, something this function has hard-coded.

16 May 2011 Optical_bench Optical_bench - a simple ray-tracing tool for optical systems. Author: Bjorn Gustavsson Wagner, Don

I adapted this to test Fresnel Prisms (Rainbow Concentrators) and it was very usefull.
