I see a more complicated thread on a similar sounding question, but my question is simpler, I hope.
I have a large numpy matrix, initially created as: Mat = zeros((a,b), int) and a smaller array with other data Sub = [1,2,3,4,5],[6,7,8,9,0] I want to replace a section of Mat matrix with Sub matrix without having to loop through each cell in each matrix individually. I thought index/slice assignments, should be able to do that, but I can only get it to work (as per book examples) with simple arrays. Every syntax combination I have tried gives one error or another, typically "can't broadcast an object....", but intuitively it seems there should be a simple solution. In short, how do I insert the data in the two (or any number of) rows in Sub[0:2] into any part of Mat starting at Mat[x,y] without using "for" loops ? -- http://mail.python.org/mailman/listinfo/python-list
