e-invert

▸ function eInvert (p: number[][]): number[][]

Defined in basic/expansion/e-invert.ts:17

Inverts the given polynomial (with coefficients given as Shewchuk floating point expansions) by reversing the order of the coefficients, i.e. p(x) -> x^deg(p) * p(1/x)

example

eInvert([[3],[2],[-5]]); // => [[-5],[2],[3]]

Parameters:

Name	Type	Description
p	number[][]	a polynomial with coefficients given densely as an array of Shewchuk floating point expansions from highest to lowest power, e.g. [[5],[-3],[0]] represents the polynomial 5x^2 - 3x

Returns: number[][]
