Hi all,
I have a sparse lil_matrix. I want to get the product over rows/column. Whats
the best way to achive that. I tried searching but unable to find a straight
forward function to do that in scipy.sparse. Though we have lil_matirx.sum(dim),
but no such thing for product.
Suppose i have
[[1, 1, 2],
[2, 3, 5],
[9, 0, 1 ]]
I want answer as in case of over rows: [18, 0, 10] and in case of over colums :
[2, 30, 0]
Thanks in advance,
Alind Sharma
