[Numpy-discussion] Rephrasing the question...

25 Jun 2002

      Thanks for the input on k-means clustering, but the main questionw as
actully this... If I have the following:

for i in xrange(k):
    w[i] = average(compress(C == i, V, 0))

... can that be expressed without the Python for loop? (I.e. without
using compress etc.) I want w[i] to be the average of the vectors in
V[x] for which C[x] == i...
