23 Feb 2010	Efficient Object-Oriented Kronecker Product Manipulation A class for efficient manipulation of N-fold Kronecker products in terms of their operands only. Author: Matt J	Oleg, I fixed some of the ragged text justification and uncommented some of the text. Not sure if those were the unreadabilities that you were talking about, though. The Description editor is a little unwieldy and gives me very limited control of spacing.
01 Feb 2010	MATLAB trilinear interpolation A Matlab mex function to perform trilinear interpolation. Author: Mehmet OZTURK	Have you ever tried compiling this under LCC? I get a slew of errors when I do. Visual C works fine.
31 Dec 2009	Sparse sub access This package allows to retrieve and assign values of sparse matrix in one shot. Author: Bruno Luong	Yep, that workaround fixed it. Anyway, I like it!!
31 Dec 2009	Structure Fields To Variables Tool for importing/exporting workspace variables to or from a struct. Author: Matt J	Hi urs, Thanks for the feedback. I need the loop to prevent large spacings between columns that can result when the fieldnames are of very different lengths. I also need the extra variables you mention to ensure that there will be no empty columns (a semantic point mainly). If you try your suggested code with nCols=3 and myStruct.a=1; myStruct.b=4; myStruct.cccccccc=7; myStruct.dddddddd=9; you will see what I mean.
16 Dec 2009	Sparse sub access This package allows to retrieve and assign values of sparse matrix in one shot. Author: Bruno Luong	Bruno - When I do mex -v -O setspvalmex.c I get a compilation error: Error setspvalmex.c: 626 compiler error in _kids--Bad rule number 0 C:\PROGRA~1\MATLAB\R2009B\BIN\MEX.PL: Error: Compile of 'setspvalmex.c' failed. Any idea what I'm doing wrong?

Author: Matt J	Komarov, Oleg	You may consider to edit the description since it's really unreadable. No way I'm gonna get past all those blocks of comments and those funny spaced examples.

31 Dec 2009	Structure Fields To Variables Tool for importing/exporting workspace variables to or from a struct. Author: Matt J	us	an interesting decoder... however, the code could be simplified as shown below in particular, there is no need for - various temporary vars - a loop %... fields=fieldnames(S); sname=inputname(idx); if isempty(sname), sname='S'; end nf=numel(fields); nr=ceil(nf/nCols); assigns=repmat({' '},nr,nCols); if RHS assigns(1:nf)=cellfun(@(f) [f ' = ' sname '.' f '; '],fields,'uni',0); else assigns(1:nf)=cellfun(@(f) [sname '.' f ' = ' f '; '],fields,'uni',0); end assigns=reshape(char(assigns.').',[],nr).'; just a thought... us
