Hi! I have a large M x K, M, K ~ 1e3 array L of indices - non-negative integers in the range 0 to N-1 - and an N x 3 array C (a matplotlib colormap). I need to create an M x K x 3 array R such that R[m,k,j] = C[L[m,k], j], j = 0,1,2. I want to do so w/out having to loop through all the (m,k) index pairs, but I'm having trouble wrapping my brain around how to do it - please help. Thanks.
DG
