dpnp.cos

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

Trigonometric cosine, element-wise.

For full documentation refer to numpy.cos.

Returns:

out – The cosine of each element of x.

Return type:

dpnp.ndarray

Limitations

Parameter x is only supported as either dpnp.ndarray or dpctl.tensor.usm_ndarray. Parameters where, dtype and subok are supported with their default values. Keyword argument kwargs is currently unsupported. Otherwise the function will be executed sequentially on CPU. Input array data types are limited by supported DPNP Data types.
