# numpy.hypot¶

`numpy.``hypot`(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'hypot'>

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

Equivalent to `sqrt(x1**2 + x2**2)`, element-wise. If x1 or x2 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, x2 : array_like Leg of the triangle(s). out : ndarray, 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. where : array_like, optional Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone. **kwargs For other keyword-only arguments, see the ufunc docs. z : ndarray The hypotenuse of the triangle(s).

Examples

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