dpnp.reciprocal

dpnp.reciprocal(x, out=None, where=True, order='K', dtype=None, subok=True, **kwargs)

Computes the reciprocal for each element \(x_i\) for input array x.

For full documentation refer to numpy.reciprocal.

Parameters:

• x ({dpnp.ndarray, usm_ndarray}) -- Input array, expected to have a floating-point data type.

• out ({None, dpnp.ndarray, usm_ndarray}, optional) --

  Output array to populate. Array must have the correct shape and the expected data type.

  Default: None.

• order ({None, "C", "F", "A", "K"}, optional) --

  Memory layout of the newly output array, if parameter out is None.

  Default: "K".

Returns:

out -- An array containing the element-wise reciprocals. The returned array has a floating-point data type determined by the Type Promotion Rules.

Return type:

dpnp.ndarray

Limitations

Parameters where and subok are supported with their default values. Keyword argument kwargs is currently unsupported. Otherwise NotImplementedError exception will be raised.

Calculate \(\frac{1}{\sqrt{x}}\), element-wise.

Notes

This function is equivalent to \(\frac{1}{x}\), element-wise.

Examples

>>> import dpnp as np
>>> x = np.array([1, 2., 3.33])
>>> np.reciprocal(x)
array([1.0, 0.5, 0.3003003])
