companion	Creates the matrix whose eigenvalues are the roots.
convert	Rewrites coefficients in the requested basis.
der	Applies differentiation repeatedly to reach the order.
div	Performs polynomial long division.
domain	Reports bounds, maps values, or trims trailing zeros.
evaluate	Computes polynomial values using Horner iteration.
fit	Solves a least squares system for the coefficients.
gauss	Computes nodes and weights for a quadrature family.
grid	Computes polynomial values at grid intersections.
int	Applies integration repeatedly to reach the order.
line	Creates coefficients for a straight line.
mul	Convolves the coefficient arrays together.
pow	Uses repeated squaring for the polynomial power.
root	Finds root values or the derived root polynomial.
sample	Evaluates a polynomial or callback over sample points.
sub	Aligns coefficients and subtracts them entry by entry.
