03 Jul 2009	EditorMacro - assign a macro to a keyboard key-stroke in the Matlab Editor and Command Window EditorMacro assigns a macro or action to requested key-binding in the Matlab Editor & Command Window Author: Yair Altman	I have tried again today. It "magically" works. Yes, it does with with the Matlab R2008A. I must say I love this feature.
02 Jul 2009	EditorMacro - assign a macro to a keyboard key-stroke in the Matlab Editor and Command Window EditorMacro assigns a macro or action to requested key-binding in the Matlab Editor & Command Window Author: Yair Altman	Exellent Work. It works with R2009A (Trial). Brillian Features! (not for me at moment). Unfornuately, it does not work with my R2008A.

06 Nov 2009	NURBS Converted NURBS toolbox	Ocean Yang	Great work! However, I find a problem in computing the first derivatives for B-spline curves/surfaces with inner multiple-knots, e.g., [0 0 0 0.5 0.5 1 1 1]. When I evaluate the first derivatives at u=0.5, it seems wrong.	4
07 Oct 2009	NURBS Converted NURBS toolbox	Eric Trautmann	I found a copy of the NURBS toolbox (for 2006b) here: http://webscripts.softpedia.com/script/Scientific-Engineering-Ruby/Mathematics/nurbs-33691.html Does anyone know if there's a newer version of this?	Comment only

24 Aug 2009	NURBS Converted NURBS toolbox	haidi	The link to the original NURBS library no longer works. http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=312&objectType=file Could anyone could upload it again? Thanks	Comment only
14 Apr 2009	NURBS Converted NURBS toolbox	Jesper	I've had the same problems with the weights and fixed it in this way: In bspeval.m between line 45 and 46, I've inserted: for i=0:d N(i+1) = N(i+1)*c(4,tmp1+i); end N = N / sum(N); This code applies the weights, but there is still a problem with nrbplot.m, but this is fixed by changing line 101 from p = nrbeval(nurbs,linspace(0.0,1.0,subd)); to [p, ggg] = nrbeval(nurbs,linspace(0.0,1.0,subd)); Where ggg is some variable, which isnt used afterwards. Besides these small errors, this code is great. Maybe there are more error, but this works for me for now.	5
