isort!

Syntax

isort!(X, [ascending=true], indices)

Arguments

X is a vector or a tuple of vectors of the same length.

ascending is a Boolean scalar indicating whether to sort X (or vectors of X sequentially) in ascending order or descending order. The default value is true (ascending order).

indices is a vector of the same length as each vector in X.

Details

isort!(x, ascending, y) is equivalent to y[isort(x, ascending)]. The result is assigned to y.

Examples

$ x=3 1 NULL 2
$ y=5 7 8 3
$ isort!(x, false, y);
[5, 3, 7, 8]
// after sorted, x is [3, 2, 1, NULL], the first element 3 is corresponding to 5 in y, the second element 2 is corresponding to 3 in y, the third element 1 is corresponding to 7 in y, ... and so on.

$ x=2 2 1 1
$ y=2 1 1 2
$ isort!([x,y],[1,0],5 4 3 2);
[2,3,5,4]
