# mindspore.numpy.polyint¶

mindspore.numpy.polyint(p, m=1, k=None)[source]

Returns an antiderivative (indefinite integral) of a polynomial.

Note

Numpy object poly1d is currently not supported.

Parameters
• p (Union[int, float, bool, list, tuple, Tensor) – Polynomial to integrate. A sequence is interpreted as polynomial coefficients.

• m (int, optional) – Defaults to 1, Order of the antiderivative.

• k (Union[int, list of int]y, optinoal) – Integration constants. They are given in the order of integration: those corresponding to highest-order terms come first. If None (default), all constants are assumed to be zero. If m = 1, a single scalar can be given instead of a list.

Returns

Tensor, a new polynomial representing the antiderivative.

Raises

ValueError – if p has more than 1 dimensions.

Supported Platforms:

Ascend GPU CPU
