[SciPy-user] weave and large arrays

[Ryan Krauss]

Either reading in the ascii data or using io.loadmat without using weave 
runs for over 15 minutes (I have shut the process down each time and 
don't know how long it takes to complete).  The *.mat file contains 11 
column vectors that are 25000 elements long.
