I have a 2D array, and want to treat each row (or column) as a vector and find norm of it a = [1 2 3 ; 4 5 6] a 2×3 Array{Int64,2}: 1 2 3 4 5 6 The following is what I have tried and their results. Both norm.(a) and vecnorm.(a) gives 2×3 Array{Int64,2}: 1 2 3 4 5 6 While norm(a) gi…

There is currently no direct function to take the norm of a 2D array by dimension. The easiest way would probably be to do either of the 2 functions below: julia> A = rand(5,4); julia> f1(A,d=1) = sqrt.(sum(abs2,A,d)) f1 (generic function with 1 method) …
