07 May 2013 export_fig Exports figures nicely to a number of vector & bitmap formats. Author: Oliver Woodford

IMO this should be built in into matlab releases.
17 Apr 2013 unique with tolerance Similar to Unique, gives unique element within a tolerance. Author: Siyi Deng

a: On my machine

uniquetol(x,0.09,'rows')

ans =

0.5000 0 0.2685
1.0000 0.2352 0.2381
1.0000 0 0.2382

Which seems correct, so I can't reproduce your problem.
17 Apr 2013 octree - partitioning 3D points into spatial subvolumes OcTree recursively splits a large set of points into smaller subvolumes. A QuadTree but in 3D. Author: Sven

great tool!
13 Oct 2010 mex_sepsq Fast, dedicated, code to compute Euclidean separation between sets of points in N-dimensional space. Author: Ben Mitch

Great function, but its kinda unnatural to use D x N and D x M column vectors. I would argue that the dimensionality should form the columns, so N x D and M x D looks more appropriate.

I think the code has some bug. Consider the set of points

x=[0.500000000000000 0 0.268506699101646;
1.00000000000000 0.235229930032594 0.238114317315998;
1.00000000000000 0 0.238161000653554;
0.500000000000002 0 0.268506699101647;
1 0.235229930032592 0.238114317315997;
1 0 0.238161000653554];

For any tolerance less than 0.1, the code produces

z = [0.500000000000000 0 0.268506699101646;
1 0.235229930032592 0.238114317315997;
1 0 0.238161000653554;
1.00000000000000 0.235229930032594 0.238114317315998;
1.00000000000000 0 0.238161000653554];

which is incorrect!

Excellent.thanks
13 Jan 2013 unique with tolerance Similar to Unique, gives unique element within a tolerance. Author: Siyi Deng Soria, Manel

After a long execution of another script that calls many times uniquetol, it crashed:

Index exceeds matrix dimensions (line 33):
z = y(isTol,:);

This happened twice and I don't see what can be the origin as I can't have the data that caused the crash. If it is an error of uniquetol I don't see it

Any suggestion ?
