Bases: ABC

_abc_impl = <_abc._abc_data object>#
argsort(*, axis=-1, descending=False, stable=True, out=None)[source]#

ivy.Array instance method variant of ivy.argsort. This method simply wraps the function, and so the docstring for ivy.argsort also applies to this method with minimal changes.

Parameters:

  • self (Array) – input array.

  • axis (int, default: -1) – axis along which to sort. If set to -1, the function must sort along the last axis. Default: -1.

  • descending (bool, default: False) – sort order. If True, the returned indices sort x in descending order (by value). If False, the returned indices sort x in ascending order (by value). Default: False.

  • stable (bool, default: True) – sort stability. If True, the returned indices must maintain the relative order of x values which compare as equal. If False, the returned indices may or may not maintain the relative order of x values which compare as equal (i.e., the relative order of x values which compare as equal is implementation-dependent). Default: True.

  • out (Optional[Array], default: None) – optional output array, for writing the result to. It must have the same shape as input.

Return type:

Array

Returns:

ret – an array of indices. The returned array must have the same shape as x. The returned array must have the default array index data type.

Examples

>>> x = ivy.array([1, 5, 2])
>>> y = x.argsort(axis=-1, descending=True, stable=False)
>>> print(y)
ivy.array([1, 2, 0])

>>> x = ivy.array([9.6, 2.7, 5.2])
>>> y = x.argsort(axis=-1, descending=True, stable=False)
>>> print(y)
ivy.array([0, 2, 1])
msort(*, out=None)[source]#

ivy.Array instance method variant of ivy.msort. This method simply wraps the function, and so the docstring for ivy.msort also applies to this method with minimal changes.

Parameters:

  • self (Array) – input array.

  • out (Optional[Array], default: None) – optional output array, for writing the result to.

Return type:

Array

Returns:

ret – sorted array of the same type and shape as a

Examples

>>> a = ivy.asarray([[8, 9, 6],[6, 2, 6]])
>>> a.msort()
ivy.array(
    [[6, 2, 6],
    [8, 9, 6]]
    )
searchsorted(v, /, *, side='left', sorter=None, ret_dtype='int64', out=None)[source]#

ivy.Array instance method variant of ivy.searchsorted.

This method simply wraps the function, and so the docstring for ivy.searchsorted also applies to this method with minimal changes.

Return type:

Array

sort(*, axis=-1, descending=False, stable=True, out=None)[source]#

ivy.Array instance method variant of ivy.sort. This method simply wraps the function, and so the docstring for ivy.sort also applies to this method with minimal changes.

Return type:

Array

Examples

>>> x = ivy.array([7, 8, 6])
>>> y = x.sort(axis=-1, descending=True, stable=False)
>>> print(y)
ivy.array([8, 7, 6])

>>> x = ivy.array([8.5, 8.2, 7.6])
>>> y = x.sort(axis=-1, descending=True, stable=False)
>>> print(y)
ivy.array([8.5, 8.2, 7.6])
