public void set(double[] x,
 double newResult)

Description copied from interface: Func.Updatable

Correct some of x arguments so that get(x) will be, as possible, equal to newResult. For example, if this is one-argument function f(x), and its inverse function is g(y) (g(f(x))=x), then this method should assign x[0]=g(newResult).

This method does not guarantee the precise equality get(x)==newResult. (Usually, it is impossible due to limited precision of floating-point calculations.) But this method should try to provide this equality (after its call) with, as possible, maximal possible precision.

Specified by:

set in interface Func.Updatable

Parameters:

x - the function arguments.

newResult - the desired function result.
