Fonction copyto - module numpy.matlib

Signature de la fonction copyto

Description

help(numpy.matlib.copyto)

copyto(dst, src, casting='same_kind', where=True)

Copies values from one array to another, broadcasting as necessary.

Raises a TypeError if the `casting` rule is violated, and if
`where` is provided, it selects which elements to copy.

Parameters
----------
dst : ndarray
    The array into which values are copied.
src : array_like
    The array from which values are copied.
casting : {'no', 'equiv', 'safe', 'same_kind', 'unsafe'}, optional
    Controls what kind of data casting may occur when copying.

    * 'no' means the data types should not be cast at all.
    * 'equiv' means only byte-order changes are allowed.
    * 'safe' means only casts which can preserve values are allowed.
    * 'same_kind' means only safe casts or casts within a kind,
      like float64 to float32, are allowed.
    * 'unsafe' means any data conversions may be done.
where : array_like of bool, optional
    A boolean array which is broadcasted to match the dimensions
    of `dst`, and selects elements to copy from `src` to `dst`
    wherever it contains the value True.

Examples
--------
>>> import numpy as np
>>> A = np.array([4, 5, 6])
>>> B = [1, 2, 3]
>>> np.copyto(A, B)
>>> A
array([1, 2, 3])

>>> A = np.array([[1, 2, 3], [4, 5, 6]])
>>> B = [[4, 5, 6], [7, 8, 9]]
>>> np.copyto(A, B)
>>> A
array([[4, 5, 6],
       [7, 8, 9]])
