Try foo[[0,2]]. Note that the array indexing syntax is a little picky: foo[(0,2)] (tuple index) won't work, just foo[[0,2]] (list index) or foo[array([0,2])] (array index).
Thanks. I see this extracts the relevant rows. How about columns?
I think for columns you need to transpose the matrix or use take() with the right axis=1.
Also, where is this documented?
pp 35,36,37,49,50,51
I spent quite a while poring over the numarray documentation. The section on index arrays looked relevant but I found it difficult to understand.
That's probably a corollary to the fact that index arrays, put, and take *are* a little difficult to understand, even more so in numarray than in Numeric. Regards, Todd
