comment compute the gradient in high dimension
`@Jens,Very general and comprehensive. I think the 2 in the first gradFilter function should be n. The code I provided is a little more efficient for 2 dimensional data though. :-)

Oh! I missed it. Thanks. I might close this question.

Because of triangle inequality, no two edges of the optimal matching can cross each other. /*A Survey on Algorithms for Euclidean Matching*/

comment Generate nonoverlapping random circles
'@Mark Adler, thanks. Your method is faster than mine(especially when n is large), and the generated circles are close to uniform distribution.

comment Generate nonoverlapping random circles
'@bill s, Thanks. A minor flaw is that the number of circles cann't be guaranted(suppose I want n circles, and n is large). I propose to use this method how-to-generate-random-points-in-a-region when the distribution is dense.
