▸ function changeVariablesScale (p: number[], a: number): number[]

Defined in change-variables/double/change-variables-scale.ts:19

Returns the result of performing a change of variables of the form: p(x) <- p(ax) in double precision.

example

changeVariablesScale([1,2,7], 3); //=> [9, 6, 7]

Parameters:

NameTypeDescription
pnumber[]a polynomial with coefficients given densely as an array of double floating point numbers from highest to lowest power, e.g. [5,-3,0] represents the polynomial 5x^2 - 3x
anumbera scaling factor, i.e. the a in p(x) <- p(ax)
