[Pw_forum] U calculation error

Dear Peng,

I'm not sure what the problem could be. sounds like a problem with the
memory of your computer.
I don't know what the line you report below is supposed to mean. NaN
usually comes out when the code tries to divide something by 0, or
things like that. try to track it in the source of the code and make
it print the quantities it uses to compute that output entry.
Have you tried to increase the max size of the matrices, or to
increase the threshold values within which the code assumes two
distances to be the same?

Matteo
