This algorithm generates one or more realisations
of \Matern's Model I
inhibition process inside the window `win`

.

The process is constructed by first
generating a uniform Poisson point process of “proposal” points
with intensity `kappa`

. If `stationary = TRUE`

(the
default), the proposal points are generated in a window larger than
`win`

that effectively means the proposals are stationary.
If `stationary=FALSE`

then the proposal points are
only generated inside the window `win`

.

A proposal point is then deleted if it lies within `r`

units' distance
of another proposal point. Otherwise it is retained.

The retained points constitute \Matern's Model I.

A point pattern
if `nsim=1`

, or a list of point patterns if `nsim > 1`

.
Each point pattern is normally an object of class `"ppp"`

,
but may be of class `"pp3"`

or `"ppx"`

depending on the window.
