Contract the grid if the evaluation points exceed some threshold.
This removes the corresponding z values.
We can add points back to achieve the same (approximate) length.
Usage
contract_grid(z, Fz, lower, upper, add_back = TRUE, monotone = TRUE)
Arguments
- z
grid points (ordered)
- Fz
function evaluated at those grid points
- lower
lower threshold at which to check Fz
- upper
upper threshold at which to check Fz
- add_back
logical; if true, expand the grid to
(about) the original size
- monotone
logical; if true, enforce monotonicity
on the expanded grid
Value
a list containing the grid points z and the (interpolated) function
Fz at those points
