e-change-variables-linear
▸ function eChangeVariablesLinear
(p: number[][], a: number, b: number): number[][]
Defined in change-variables/expansion/e-change-variables-linear.ts:31
Returns the exact result (bar underflow / overflow) of performing a change of variables of the form: p(x) <- p(ax + b) on the given polynomial (with coefficients given as Shewchuk expansions).
example
eChangeVariablesLinear([[1],[2],[7]], 3, 4); //=> [[9], [30], [31]]
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 |
a | number | the a in ax + b |
b | number | the b in ax + b |
Returns: number[][]
