Polynomial

Evaluates a polynomial whose coefficients are supplied in descending powers.

Behavior

p(x) = aₙxⁿ + … + a₁x + a₀. The worked example connects this operation to signals in Lemonergy Studio.

Original Lemonergy interface view. Lines identify ports; they are not a completed simulation circuit.

Ports and observed outputs
Name	Direction	Unit	Meaning
`in0`	input	1	x; real scalar.
`out0`	output	1	Polynomial value; real scalar.

Defaults are initial model values. Select values for your own model and operating conditions.

Configuration fields
Parameter	Unit	Default	Meaning and limits
Coefficients `tables[0]`	1	[2, -3, 1]	Descending powers: aₙ, …, a₁, a₀.

x = 3. Polynomial value at 0 s = 10.

- Use the block reference for settings and connections.
- Implementation tested locally; public release pending.

Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.

This software operation and its numerical conventions are defined by the public contract and worked example; no external research result is claimed.

This reference follows the public interface and locally verified numerical checks for an upcoming release.
