27 Oct 2009	rot90 in 3D This function extends the rot90 command to 3D. Author: Matt Fetterman	Hi Jan, Thanks for comments. I did update it. It is hard to write it using the permute command but hopefully got it right !
26 Sep 2009	SORTFIELDS SORTFIELDS sort values in all fields within a structure. Author: Ian Howat	Seems quite useful !
03 Sep 2009	Better Skeletonization Provides an alternative to the image toolbox skeletonization implemented in bwmorph. Author: Nicholas Howe	It is very good. I have suggestions for additional features if you are interested in collaboration.
03 Sep 2009	tree labelling simple and new algorithm for labellings of 3 level trees Author: Alireza Fasih	It is a very good program. I have suggestions if you are interested in collaboration.

13 Nov 2009	Anaskel written in Matlab Translated anaskel.cpp into Matlab Author: Matt Fetterman	Howe, Nicholas	Good idea to port this to a .m file. Thanks for doing it!
04 Nov 2009	rot90 in 3D This function extends the rot90 command to 3D. Author: Matt Fetterman	Simon, Jan	Some indices are confused: Dim=2 and 3, NumRot=1 and 3. I've used your correct working first submission for checking the results. I'll try to contact you by email.

26 Oct 2009	rot90 in 3D This function extends the rot90 command to 3D. Author: Matt Fetterman	Simon, Jan	Sorry - I forgot some indices: Y = ROT90_3D(X,1,1) equals: M = PERMUTE(X, [1,3,2]); Y = M(:, size(X,3):-1:1, :); Other equivalents: ROT90_3D(X, 1, 2): Y = X(:, size(X, 2):-1:1, size(X, 3):-1:1); ROT90_3D(X, 1, 3): Y = PERMUTE(X(:, size(X,2):-1:1, :), [1,3,2]); For the other dimensions, this formulas are cyclical shifted. For e.g. [100 x 100 x 100] arrays this takes about 2% of the time of ROT90_3D, so I'd suggest to update the submission.
15 Oct 2009	rot90 in 3D This function extends the rot90 command to 3D. Author: Matt Fetterman	Simon, Jan	Help text exist, but not at the usual position. No H1-line, no check of inputs. The 3rd argument of ROT90 is optional, so a user might expect this for ROT90_3D also. The calculations are valid, but not efficient due to using loops. E.g. for M=ROT90_3D(X,1,1) this is faster: A=PERMUTE(X,[1,3,2]); M=A(:,size(X,3),:); Further acceleration: Use same array name for input and output (see: Loren's blog "In-place Operations on Data").
