multi_stage_ODE: Multi-stage ODE

In Andreaierardi/disCOVIDer19: Covid_19 outbreak analysis

Description

Solve an ODE with time-varying parameter msp (multi stage parameter) and time fixed parameters parameters.

Usage

multi_stage_ODE(U0, func, var_names, par_fixed, msp, msp_name, L, time_step)

Arguments

U0	named list. Initial conditions at time 0
func	function. Given U array of variables, func(U;parameters) = dU/dt
var_names	list of char. The names of the variable as in func
par_fixed	named list. The format is ('name'=value)
msp	array like. Contains all the values assumed by the time variable parameters
msp_name	char. Name of the msp as appearing in func
L	array like. Contains the extreme of use of the components of msp. msp[n] is the msp in use from L[n-1] to L[n]. The last component of L is the final point of integration
time_step	float. Step of integration

Value

a list:

sol

dataframe. Solution to ODE evaluated at $times

time

array like. Points of evaluation of solution
