Method Details

### __init__(self, x, *cs) (Constructor) |
New Fhorner evaluation of the polynomial sum(cs[i] * x**i for i=0..len(cs)). Parameters: `x` - Polynomial argument (`scalar`). `cs` - Polynomial coeffients (`scalar`[]). Raises: `TypeError` - Non-scalar x. `ValueError` - No cs coefficients or x is not finite. Overrides: object.__init__ See Also: Function fhorner.
