12 Nov 2012 Matlab to Google Spreadsheets Matlab functions to send data to Google Spreadsheets. Author: Claudiu Giurumescu

If any current users are interested in a binary stl import, please let me know.

22 Mar 2011 LAPJV - Jonker-Volgenant Algorithm for Linear Assignment Problem V3.0 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Does anyone know if there's a newer version of this?

02 Nov 2014 Fast STL import function Function to import .stl geometry model files into matlab. Author: Eric Trautmann Fritz

@Pierrick Bersier: I'm getting the same error.

06 Sep 2014 Fast STL import function Function to import .stl geometry model files into matlab. Author: Eric Trautmann Pierrick Bersier

When I try to load my STL with that script, I get every time the same error. an sombody help ?

Subscript indices must either be real positive integers or logicals.

Error in import_stl_fast (line 59)
if (C{4}(end)== NaN)

28 Aug 2013 Fast STL import function Function to import .stl geometry model files into matlab. Author: Eric Trautmann Emmanuel Farhi

Works OK for ASCII STL files. Thanks.
