Lecture 3: Solving Equations Using Fixed Point Iterations
pages.cs.wisc.edunumeric solution r. In a previous lecture, we introduced an iterative process for finding roots of quadratic equations. We will now generalize this process into an algorithm for solving equations that is based on the so-called fixed point iterations, and therefore is referred to as fixed point algorithm. In order to use fixed point ...
