fastIterate: Accelerate a point iteration

In pdmetcalfe/extrapolatr: Convergence Acceleration

Description

Use the techniques from this package to accelerate a point iteration.

Usage

fastIterate(start, f, method, n.prior, pre.iter, num.accel, num.cycles, ...)

Arguments

start	the start value
f	the function to iterate
method	the acceleration function. must take an m x n matrix and return an m-vector.
n.prior	the number of prior iterations to run before accelerating
pre.iter	how many iterations to do before acceleration (per cycle)
num.accel	how many iterations to accelerate
num.cycles	how many cycles to do?
...	additional arguments for f

Examples

fastIterate(c(0.2, 0.6), function(x) {c(1 - sin(x[[1]]), cos(x[[2]]))},
            rre, 1, 3, 5, 10)
