Hi all,
Thanks for all of the answers, it gives me a lot of new ideas and new
functions I didn't know of.
@Charles:
The reshape way is a great idea! It gives a great alternative to the
for loop for your code to be vectorized. I tested it I get
%timeit scale_and_add_reshape(R,w,Msr)
1 loops, best o

Thanks for the prompt reply!
I quickly tried that and it actually helps compared to the full
vectorized version.
Depending on the dimensions, the chunk size has to be tuned (typically
100 or so)
But I don't get any improvement w/r to the simple for loop (i can
almost match the time though).
My gue

Hi all,
First email to the list for me, I just want to say how grateful I am
to have python+numpy+ipython etc... for my day to day needs. Great
combination of software.
Anyway, I've been having this bottleneck in one my algorithms that has
been bugging me for quite a while.
The objective is to sp
