# Sorting and searching¶

## Sorting¶

 sort(a[, axis, kind, order]) Return a sorted copy of an array. lexsort(keys[, axis]) Perform an indirect sort using a sequence of keys. argsort(a[, axis, kind, order]) Returns the indices that would sort an array. ndarray.sort([axis, kind, order]) Sort an array, in-place. msort(a) Return a copy of an array sorted along the first axis. sort_complex(a) Sort a complex array using the real part first, then the imaginary part.

## Searching¶

 argmax(a[, axis]) Indices of the maximum values along an axis. nanargmax(a[, axis]) Return indices of the maximum values over an axis, ignoring NaNs. argmin(a[, axis]) Return the indices of the minimum values along an axis. nanargmin(a[, axis]) Return indices of the minimum values over an axis, ignoring NaNs. argwhere(a) Find the indices of array elements that are non-zero, grouped by element. nonzero(a) Return the indices of the elements that are non-zero. flatnonzero(a) Return indices that are non-zero in the flattened version of a. where(condition, x) Return elements, either from x or y, depending on condition. searchsorted(a, v[, side]) Find indices where elements should be inserted to maintain order. extract(condition, arr) Return the elements of an array that satisfy some condition.
