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)
I am pretty sure you should be able to do
R = C[L, :] and get the array you want.
Try it with a small matrix where you know the result you want. You may need
to transpose some axes afterwards, but I don't think you should.
