tf.math.polyval(
coeffs,
x,
name=None
)
Defined in tensorflow/python/ops/math_ops.py
.
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]))
Args:
coeffs
: A list ofTensor
representing the coefficients of the polynomial.x
: ATensor
representing the variable of the polynomial.name
: A name for the operation (optional).
Returns:
A tensor
of the shape as the expression p(x) with usual broadcasting rules
for element-wise addition and multiplication applied.
