dynam_record: Simulate and record a dynamic system(Euler's Method)

In HaoLi111/rMathModeling: R Functional Programming Solution for Mathematical Modeling 4 Ed

Simulate and record a dynamic system(Euler's Method)

Description

With a interation formula, update the status state in a memory-saving way, and record the results.

Usage

dynam_record(init,index,
                        Fupdate,.combine = 'rbind',
                        record_per=1)

Arguments

init	Initial state of a system
index	Index (range) to interate within
Fupdate	Function to update current status flow (with no extra parameters).
.combine	Method to combine results. Must be character input, choose between 'rbind', 'cbind' and'list'.
record_per	Linspace division for record.

Examples

#2D Brownian Motion

dynam_runif=dynam_record(init = c(1,1),index=1:100,Fupdate=(function(x) x+rnorm(2, mean=0, sd=1)))
plot(dynam_runif[,2],dynam_runif[,3],type='l',xlab='x',ylab='y')
