mindspore.numpy.polymul

mindspore.numpy.polymul(a1, a2)[source]

Finds the product of two polynomials.

Note

Numpy object poly1d is currently not supported.

Parameters

a1 (Union[int, float, bool, list, tuple, Tensor) – Input polynomial.
a2 (Union[int, float, bool, list, tuple, Tensor) – Input polynomial.

Returns

Tensor, a new polynomial representing the derivative.

Raises

ValueError – If the input array has more than 1 dimensions.

Examples

>>> import mindspore.numpy as np
>>> print(np.polymul([3, 1, 2], [2, 5]))
[ 6 17  9 10]
