dpnp.multiply

dpnp.multiply(x1, x2, out=None, where=True, order='K', dtype=None, subok=True, **kwargs)

Calculates the product for each element x1_i of the input array x1 with the respective element x2_i of the input array x2.

For full documentation refer to numpy.multiply.

Parameters:

  • x1 ({dpnp.ndarray, usm_ndarray}) – First input array, expected to have numeric data type.

  • x2 ({dpnp.ndarray, usm_ndarray}) – Second input array, also expected to have numeric data type.

  • out ({None, dpnp.ndarray}, optional) – Output array to populate. Array must have the correct shape and the expected data type.

  • order ({"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 result of element-wise multiplication. The data type of the returned array is 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.

Notes

Equivalent to x1 * x2 in terms of array broadcasting.

Examples

>>> import dpnp as np
>>> a = np.array([1, 2, 3, 4, 5])
>>> np.multiply(a, a)
array([ 1,  4,  9, 16, 25])]

>>> x1 = np.arange(9.0).reshape((3, 3))
>>> x2 = np.arange(3.0)
>>> np.multiply(x1, x2)
array([[  0.,   1.,   4.],
       [  0.,   4.,  10.],
       [  0.,   7.,  16.]])

The * operator can be used as a shorthand for multiply on dpnp.ndarray.

>>> x1 * x2
array([[  0.,   1.,   4.],
       [  0.,   4.,  10.],
       [  0.,   7.,  16.]])
