fracsim.2d {FracSim} | R Documentation |
The function simulates 2D fractional and multifractional motions
fracsim.2d(h, n, kx, ky = kx, m = 1)
h |
Regularity function. One value for fractional motions; either a function or a kx*ky-matrix for multifractional ones |
n |
Number of terms in the serie |
kx |
Either the vector of row discretisation points or the number of points (calculated equally spaced) |
ky |
Either the vector of column discretisation points or the number of points (calculated equally spaced) |
m |
Mass term, usually set equal to 1 |
X |
kx-vector of row discretization points |
Y |
ky-vector of column discretization points |
simul.h |
Matrix of imulated regularity values |
process |
kx*ky-matrix which elements are the process value at each discretization point |
