Hi,
I’m looking a problem where I have an NxN grid of ints. I need a function like setValue x y newVal
I have tried using [[Int]] but it does become messy when splitting , dropping and then ++ back together.
What other options are available to represent a mutable grid?
Mutable vectors (from the vector[1] package) are an obvious choice. When I had to do something similar, I wound up going all the way to repa[2], which magically turns all of your grid operations into parallel ones.
