I have arrays with 2 dimensions. Elements in the arrays are only considered valid for certain values on the indices. For example, consider the arrays A and B below: A = round.(rand(10, 2) .* 100) A[1:3, 2] .= NaN B = round.(rand(10, 2) .* 100) B[1:3, 2] .= NaN If it helps, you can think of the arr…

Try also Cartesian Indices: CI = filter(x -> x ∉ CartesianIndices((1:3,2:2)), CartesianIndices(A)) s = sum(A[I]*B[I] for I in CI)

How can I easily skip indices in an array?
