all_roots: Finds all roots of a function within an interval

In mrc-ide/epihawkes: Hawkes Processes model for outbreak analysis

Description

Searches the interval from lower to upper for all roots of a function f with respect to its first argument. Based on rootSolve::uniroot.all.

Usage

all_roots(
  f,
  interval,
  lower = min(interval),
  upper = max(interval),
  tol = .Machine$double.eps^0.2,
  maxiter = 1000,
  trace = 0,
  n = 1000,
  ...
)

Arguments

f	The function for which the root is sought..
interval	A vector containing the end-points of the interval to be searched for the root.
lower	Lower end point of interval.
upper	Upper end point of interval.
tol	Desired accuracy of root
maxiter	Maximum number of iterations
trace	Integer number passed to function uniroot. If positive, tracing information is produced. Higher values giving more details.
n	Number of subintervals in which the root is sought.
...	Additional named or unnamed arguments to be passed to f.
