Polynomial API Reference

The poly module provides functions for polynomial arithmetic and evaluation.

Evaluation

polyval

Evaluate a polynomial at specific values.

pub fn polyval(allocator: Allocator, comptime T: type, p: NDArray(T), x: NDArray(T)) !NDArray(T)

Arithmetic

polyadd

Add two polynomials.

pub fn polyadd(allocator: Allocator, comptime T: type, p1: NDArray(T), p2: NDArray(T)) !NDArray(T)

polysub

Subtract two polynomials.

pub fn polysub(allocator: Allocator, comptime T: type, p1: NDArray(T), p2: NDArray(T)) !NDArray(T)

polymul

Multiply two polynomials.

pub fn polymul(allocator: Allocator, comptime T: type, p1: NDArray(T), p2: NDArray(T)) !NDArray(T)

Calculus

polyder

Return the derivative of the specified order of a polynomial.

pub fn polyder(allocator: Allocator, comptime T: type, p: NDArray(T), m: usize) !NDArray(T)

polyint

Return an antiderivative (indefinite integral) of a polynomial.

pub fn polyint(allocator: Allocator, comptime T: type, p: NDArray(T), m: usize, k: T) !NDArray(T)

Roots

roots

Return the roots of a polynomial with coefficients given in p.

pub fn roots(allocator: Allocator, comptime T: type, p: NDArray(T)) !NDArray(T)
