![]() The by keyword lets you provide a function that will be applied to each element before comparison the lt keyword allows providing a custom "less than" function (note that for every x and y, only one of lt(x,y) and lt(y,x) can return true) use rev=true to reverse the sorting order. You can select a specific algorithm to use via the alg keyword (see Sorting Algorithms for available algorithms). Sort!(v alg::Algorithm=defalg(v), lt=isless, by=identity, rev::Bool=false, order::Ordering=Forward) The isless function is invoked by default, but the relation can be specified via the lt keyword. If needed, the sorting algorithm can be chosen: julia> sort(v, alg=InsertionSort)Īll the sorting and order related functions rely on a "less than" relation defining a total order on the values to be manipulated. Or in reverse order by a transformation: julia> sort(v, by=abs, rev=true) Instead of directly sorting an array, you can compute a permutation of the array's indices that puts the array into sorted order: julia> v = randn(5)Īrrays can easily be sorted according to an arbitrary transformation of their values: julia> sort(v, by=abs) Use the "bang" version of the sort function to mutate an existing array: julia> a = Sort constructs a sorted copy leaving its input unchanged. You can easily sort in reverse order as well: julia> sort(, rev=true) By default, Julia picks reasonable algorithms and sorts in standard ascending order: julia> sort() Julia has an extensive, flexible API for sorting and interacting with already-sorted arrays of values.
