```def cgqp(QuadPoint, TrngleNode, a):
c = Numeric.take(a.NodeCord, TrngleNode)

This may or may not be right. The data structures I would have to set up
to test it are too much for Sunday morning.

Subject: [Numpy-discussion] Can this function by Numpy-ized?

I finally got my FEM EM code working.  I profiled it and this function
uses up a big hunk of time.  It performs gaussian integration over a
triangle.  I am trying to figure out how to slice the arrays so as to
push it down into the C level.  Does anyone have any ideas?  Thanks,
Rob.

ps. it looks to be intractible to me.  Maybe I need to look at writing a
C extension.  I've never done that before.

##Description: To compute the coordinates of 7-point Gauss nodes of
##             a triangular patch.
##Input value:
##    int QuadPoint  --- node index, it can be from 0 to 6.
##    int *a.TrngleNode  ---  the three nodes of a tringular patch.
##    double *SrcPointCol --- where to store the results
##Return value: none
##Global value used: a.NodeCord, a.Qpnt
##Global value modified:    none
##Subroutines called:    none
##Note: Not very sure.
