mindspore.numpy.polyval
- mindspore.numpy.polyval(p, x)[source]
Evaluates a polynomial at specific values. If p is of length N, this function returns the value:
p[0]*x**(N-1) + p[1]*x**(N-2) + ... + p[N-2]*x + p[N-1]
If x is a sequence, thenp(x)
is returned for each element of x. If x is another polynomial then the composite polynomialp(x(t))
is returned.Note
Numpy object poly1d is currently not supported.
- Parameters
- Returns
Tensor.
- Raises
ValueError – if p has more than 1 dimensions.
- Supported Platforms:
