Apply optimization function by coordinate shifting

Description

By repeating the process of optimization on each coordinate, find the minimum of a multi-variable function.

Usage

ply_shift_coord(fListPly,iter = list(x = c(1,3),
                                         y = c(0,2),
                                         z = c(-1,4)),
                           init = list(x=1,y=1.5,z = 1),
                           optimFunc = optim_midp,nply_iter = 5,...)

Arguments

fListPly	A function taking in a list of corresponding variable
iter	Iteration parameters for the optimFunc
init	Initial value to take in
optimFunc	Method to optimize a 1 var func.

Details

May converge quickly if the function does not have more than 1 local variables.
