dask.array.hypot

dask.array.hypot(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, _subok=True_[, _signature_]) = <ufunc 'hypot'>

This docstring was copied from numpy.hypot.

Some inconsistencies with the Dask version may exist.

Given the “legs” of a right triangle, return its hypotenuse.

Equivalent to sqrt(x1**2 + x2**2), element-wise. If x1 orx2 is scalar_like (i.e., unambiguously cast-able to a scalar type), it is broadcast for use with each element of the other argument. (See Examples)

Parameters

x1, x2array_like

Leg of the triangle(s). If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).

outndarray, None, or tuple of ndarray and None, optional

A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.

wherearray_like, optional

This condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the defaultout=None, locations within it where the condition is False will remain uninitialized.

**kwargs

For other keyword-only arguments, see theufunc docs.

Returns

zndarray

The hypotenuse of the triangle(s). This is a scalar if both x1 and x2 are scalars.

Examples

import numpy as np
np.hypot(3np.ones((3, 3)), 4np.ones((3, 3)))
array([[ 5., 5., 5.], [ 5., 5., 5.], [ 5., 5., 5.]])

Example showing broadcast of scalar_like argument:

np.hypot(3*np.ones((3, 3)), [4])
array([[ 5., 5., 5.], [ 5., 5., 5.], [ 5., 5., 5.]])
