I need to bang out an image processing library (it's schoolwork, so I
can't just use an existing one). But I see three libraries competing
for my love: numpy, numarray, and numeric.

BTW, numpy is replacing numarray, so if you're just get
nates individually,
for speed and ufuncs
numarray fits the bill perfectly, especially since system.coordinates
[4] would return proper vector for a 5th point.
To start, read the coordinates from a text file and add them to our
array one by one.

Ahh, I figured it out. The key is to set up the shapes so they
broadcast like an outerproduct, but using bitwise_and as the operation
and the second operand as the bit filter. So we temporarily expand
each bit to a byte for numarray to be able to use it for dot products.
If you use a temporary
I need to be able to store thousands of one-million-length bit arrays.
The first operations use the & operator. But eventually I must perform
an inner product with a one-million-length integer array (summing at
all the indices of the integer operand where the boolean operand has a
"1").
