Fixed Points for Functions of Several Variables

Fixed-point iteration - Wikipedia
https://en.wikipedia.org/wiki/Fixed-point_iterationIn numerical analysis, fixed-point iteration is a method of computing fixed points of a function. More specifically, given a function defined on the real numbers with real values and given a point in the domain of , the fixed-point iteration is which gives rise to the sequence which is hoped to converge to a point . If is continuous, then one can prove that the obtained is a fixed point of , i.e.,
