7.8.1 find(), findfirst(), and findnext()

Apart from just sensing the presence of a similar value, sometimes you need to find the exact position of a value inside an array. The positions are addressed by indices. The built-in function find() outputs the same. Another set of built-in functions, findfirst() and findnext(), finds a value for its first occurrence and next to a given index, respectively:

julia> A = collect(1:20); # Array having 1 to 20 numbers

julia> find(isodd,A) # Finding numbers which are odd

10-element Array{Int64,1}:
