[Numpy-discussion] 2D Arrays column operations
Thu Mar 29 15:32:17 CDT 2007
Others can correct me, but I believe the ndarrys of
numpy are *not* stored like C arrays, but rather as a
contiguous memory chunk (there are some exceptions,
but ignore for the moment). Then along with the data
is a structure that tells numpy how to "address" the
array's data memory using indices (+ other array
info). In particular, the structure tells numpy the
dimension and the strides for each dimension so it can
skip along and pick out the right components when you
I'm sure Travis will correct me if I'm off, but I
think this is basically how numpy arrays operate.
