Well, * works with numerics julia> A = [1:5] 5-element Array{Int64,1}: 1 2 3 4 5 julia> A *3 5-element Array{Int64,1}: 3 6 9 12 15
And for strings, the following works: julia> VA 3-element Array{ASCIIString,1}: "A" "B" "C" julia> VB = ["a", "b", "c"] 3-element Array{ASCIIString,1}: "a" "b" "c" julia> VA .* VB 3-element Array{ASCIIString,1}: "Aa" "Bb" "Cc" So likewise, it is better that VA * "T" should work too.
