Muller method

Muller method

[′məl·ər ‚meth·əd] (mathematics) A method for finding zeros of a function ƒ(x), in which one repeatedly evaluates ƒ(x) at three points, x1, x2, and x3, fits a quadratic polynomial to ƒ(x1), ƒ(x2), and ƒ(x3), and uses x2, x3, and the root of this quadratic polynomial nearest to x3 as three new points to repeat the process.
