R Documentation
Fractional Brownian field simulation by the midpoint displacement method
Description
The function midpoint yields simulation of sample path of a fractional Brownian field
by the midpoint displacement method.
Usage
midpoint(process)
Arguments
process
an object of class process (namely an FBm).
Details
The subspace [0,1] x [0,1] is discretized in a regular space discretization of size
(2^{code{nblevel}}+1)^2. At each point of the grid, the fractional Brownian
field is simulated using the midpoint displacement method described for example
in Fournier et al. (1982).
Value
an object of class process with the simulated sample path in the corresponding slot values.
