This seems to suffer from the same problem. A temporary arra

Does this do what you want?

When I run
import numpy as np
a = np.ones((400, 50), dtype=np.float32)
c = np.dot(a, a.T)
produces a "MemoryError" on the 32-bit Enthought Python Distribution
on 32-bit Vista. I understand this has to do with the 2GB limit with
32-bit python and the fact numpy wants a contiguous chunk of me
