tf.math.polyval

Computes the elementwise value of a polynomial.

If `x` is a tensor and `coeffs` is a list n + 1 tensors, this function returns the value of the n-th order polynomial

p(x) = coeffs[n-1] + coeffs[n-2] * x + ... + coeffs[0] * x**(n-1)

evaluated using Horner's method, i.e.

p(x) = coeffs[n-1] + x * (coeffs[n-2] + ... + x * (coeffs[1] + x * coeffs[0]))

`coeffs` A list of `Tensor` representing the coefficients of the polynomial.
`x` A `Tensor` representing the variable of the polynomial.
`name` A name for the operation (optional).

A `tensor` of the shape as the expression p(x) with usual broadcasting rules for element-wise addition and multiplication applied.
