Create a Point Db
db.point.init(ndim = 2, density=1, db=NA, extend = NA, origin = NA, range=1, beta=1, mode = "poisson", seed=122342, verbose=FALSE)
ndim |
Space Dimension. If 'origin" or 'extend' is provided, the dimension of this argument dictates the Space Dimension. |
density |
Average density of the Point Process. This parameter is used when 'mode' is set to "Poisson" or to "Poisthin". |
extend |
Vector of field extension along each space axis. This parameter is useless when argument 'db' is provided. |
origin |
Vector of field origin along each space axis. This parameter is useless when the argument 'db' is provided. |
db |
Auxiliary |
range |
Range for the repulsion function. The repulsion is given by the probability: P(r) = 1 / (1 + r^2)^beta when r stands for the distance normalized by the range. Only used when 'mode' is set to "Poisthin". |
beta |
Beta coefficient for the repulsion function. The repulsion is given by the probability: P(r) = 1 / (1 + r^2)^beta when r stands for the distance normalized by the range. Only used when 'mode' is set to "Poisthin". |
mode |
The Point Process is generated according to one of the following modes:
|
seed |
Seed used for the Random Number Generator. |
verbose |
Verbose flag |
The new Point db-class
containing the newly generated samples.
