06 Jun 2010	Edges generation Algorithm generates edges of a conforming 2D/3D triangulation. Author: Jan Valdman	Works nicely and very fast for 3D also. The updated code is even more short and elegant than before. Nice.

05 May 2009	Edges generation Algorithm generates edges of a conforming 2D/3D triangulation. Author: Jan Valdman	Greetings from Finland! Thanks for sharing this code. I have been using it alongside a 2D Nedelec-FEM implementation. This kind of code could be useful in 3D also. It seems that mesh generators always provide elements in terms of nodes, but for edge-based finite elements it is necessary to have the information in terms of edges.

26 Jul 2010	Multiple eigen-values for 2x2 and 3x3 matrices Compute in one shot the eigen-values of multiples (3 x 3) matrices using Cardan's formula	Jeff Evans	Excellent. Much faster than running eig in a for loop. Thanks!	5

05 Sep 2009	NUMUNIQUE Returns unique elements in an array and all the indices for the repetitious values.	Zhigang Xu	Ah, the explanation to the above puzzle (i.e., NaN vs Double) lies in that whenever NaN is concatenated with other classes, it will be converted to zero first. Thus, uint8(nan) ans = 0 int32(nan) ans = 0 [nan uint16([1 2])] ans = 0 1 2 whereas [nan double([1 2])] ans = NaN 1 2 A lesson to remember is that NaN is only a not-a-number within double class. It will become zero when it is converted to other classes.	Comment only
05 Sep 2009	NUMUNIQUE Returns unique elements in an array and all the indices for the repetitious values.	Zhigang Xu	This is a very thoughtful suggestion. Thanks! I did a quick experiment as follows, showing that NaN can only work with a double class to get right logical indices. I will implement your suggestion for next updating. Thanks again! >> diff([nan [0 1]])~=0 ans = 1 1 >> diff([nan uint8([0 1])])~=0 ans = 0 1	Comment only
