timevar_poly 0.1.1

timevar-poly: A lightweight engine for time-variant polynomials.

timevar-poly

A lightweight Python engine for time-variant polynomials.

Features

• Coefficients can be constants or functions of time (TimeFunction).
• Automatic constant reduction (optimizes 0, 1, and constant operations).
• Symbolic-numeric differentiation (spatial diff_x() and temporal diff_t()).
• No external dependencies.

Quick Start

from timevar_poly import TimeVariantPolynomial, TimeFunction
import math

# P(x, t) = (sin t)x + 5
P = TimeVariantPolynomial({1: TimeFunction(math.sin), 0: 5})
print(P(x=2, t=math.pi/2)) # Output: 7.0
