13 Jun 2013 Adjust window level of image using mouse button You can adjust the window level using mouse Author: Yi Sui

The updated version of your code is much nicer - thanks!
The local variables are now stored in the figure's UserData, wuch that it can be applied to multiple figures without confusions.

I still see a problem in the missing documentation. While the code does not contain a help section, the only specification is found here in the FEX: "adjust the window level". But what exactly is adjusted?

Now I think, that this function is probably useful. Only the lack of a documentation reduces the usability substantially. A small help sections with a H1-line, which decribes the inputs and the applied procedure clearly, would be enough.

12 Jun 2013 Hello/Goodbye World using GUI 2.5 Test Upload Author: Siva

Using the brute clearing header "clc; clear all;" inside the functions is a bad idea. On one hand a function does not contain local variables initially, such that clearing them does not have any benefit. On the other hand this removes all breakpoints also, and everything, which prevents debugging, is a really bad programming practize.

I prefer the standard indentation scheme applied by Matlab automatically. But this is a question of taste only.

The small number of comments reduces the educational value of this submission.

Transporting a set of variables as cell has the important drawback, that the order of the values matter:
x=temp{1,1};
y=temp{1,2};
a=temp{1,3};
If you use a struct with the fields "x", "y", and "a" instead, the meaning is immediatly clear.

I forgot to mention, that "clear all" removes all debugger breakpoints also. And everything, which impedes debugging is a bad programming practize.

MATLAB cell concatenation is extremely slow. Jan's FEX is a must for those who care about speed.
