22 Mar 2011 LAPJV - Jonker-Volgenant Algorithm for Linear Assignment Problem V2.4 A Matlab implementation of the Jonker-Volgenant algorithm solving LAPs. Author: Yi Cao

I've been using both of your Munkres and JV LAP algorithm implementations. JV is much faster for a single matrix, as expected, but I also found that when I used the JV algorithm within the Murty k-best assignment algorithm, it was much slower than your implementation of Munkres. When I dug into this, I found that the JV implementation does not cull out rows or columns all marked as inf. When I made this modification (copied the validRow/validCols lines from munkres.m), it sped up the algorithm by a factor of ~7.

08 Feb 2010 Gaussian Mixture Model (GMM) - Gaussian Mixture Regression (GMR) Encoding of data in Gaussian Mixture Model and retrieval through Gaussian Mixture Regression Author: Sylvain Calinon

This also does not work for 3D data, line 28 of plotGMM explicitly considers only the 2D case since the [cos(t) sin(t)] constrains the result to be a length(t) x 2 matrix:

X = [cos(t) sin(t)] * real(stdev) + repmat(Mu(:,j)',nbDrawingSeg,1);

The documentation appears great, but suggests that this can handle arbitrarily high dimensional cases.

07 Oct 2009 NURBS Converted NURBS toolbox Author: Daniel Claxton

I found a copy of the NURBS toolbox (for 2006b) here:

Does anyone know if there's a newer version of this?

08 Dec 2011 Faster Jonker-Volgenant Assignment Algorithm This is a modification made to Yi Cao's original JV algorithm code. Author: Eric Trautmann sim, yanchuan

hi

i ran this code on a 7036x3597 matrix and there seem to be a bug in the section where you pad the output matrix to look like munkres.

for rowind=1:size(dMat,1)
    assignment_small(rowind,rowsol(rowind))=1;
end

the error i got was the code trying to access rowsol(3598), when rowsol only has 3597 rows. It worked fine when i transposed my input data (so that there are more columns than rows).

Thanks.
