Sorting and searching


sort (a[, axis, kind, order]) Return a sorted copy of an array.
lexsort (keys[, axis]) Perform an indirect sort using a list 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.


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 along 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, y]) 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.
