In hmito/hmRLib: Helper library for numerical analysis with R

Find root of a function using small_step method

Description

This function returns roots of a focal function by checking the sign change in each step.

Usage

small_step_root(func, step, ...)

Arguments

func	the function for which the root is sought.
step	a vector containing the step values
...	optional arguments to be passed to "func"

Value

data.frame with two col, "lower" and "upper" which are the range of the solutions. root

Examples

f = function(x,y){return(x*x-y*x)}
ans = small_step_root(f, seq(-2,2,length=41),y=1.333)
# ans == data.frame("lower"=c(0.0,1.3),"upper"=c(0.0,1.4))
