Understanding arrays, matrices, and multidimensional arrays
An array is an indexable collection of objects such as integers, floats, and Booleans, which are stored in a multidimensional grid. Arrays in Julia can contain values of the Any type. Arrays are implemented internally in Julia itself.
In most of the other languages, the indexing of arrays starts with 0. In Julia, it starts with 1:
# creating an arrayjulia> simple_array = [100,200,300,400,500]5-element Array{Int64,1}:100200300400500# accessing elements in arrayjulia> simple_array[2]200julia> simple_array[2:4]3-element Array{Int64,1}:200300400
In the preceding example, we can see that, unlike other programming languages, indexes start from 1.
