# fes2: Calculate free energy surface by conventional algorithm (generic function
for 'metadynminer' and 'metadynminer3d')

## Description

`fes2` sums up hills using slow conventional algorithm. It can be used
as a reference or when hill widths are variable.

## Usage

fes2(hills, imin, imax, xlim, ylim, zlim, npoints)

## Arguments

imin

index of a hill from which summation starts (default 1).

imax

index of a hill from which summation stops (default the rest of hills).

xlim

numeric vector of length 2, giving the CV1 coordinates range.

ylim

numeric vector of length 2, giving the CV2 coordinates range.

zlim

numeric vector of length 2, giving the CV3 coordinates range.

npoints

resolution of the free energy surface in number of points.
