Observation matrix for space-time models
Description
Observation matrix for space-time models
Usage
rSPDE.Ast(
mesh_space = NULL,
space_loc = NULL,
mesh_time = NULL,
time_loc = NULL,
graph = NULL,
obs.s = NULL,
obs.t = NULL,
ind.field = NULL
)
Arguments
mesh_space |
mesh object for models on 1d or 2d domains |
space_loc |
mesh locations for models on 1d domains |
mesh_time |
mesh object for time discretization |
time_loc |
mesh locations for time discretization |
graph |
MetricGraph object for models on metric graphs |
obs.s |
spatial locations of observations |
obs.t |
time points for observations |
ind.field |
indices for field (if Dirichlet conditions are used) |
Value
Observation matrix linking observation locations to mesh nodes
Examples
s <- seq(from = 0, to = 20, length.out = 11)
t <- seq(from = 0, to = 20, length.out = 5)
n.obs <- 10
obs.loc <- data.frame(x = max(s)*runif(n.obs),
t = max(t)*runif(n.obs))
A <- rSPDE.Ast(space_loc = s,time_loc = t,
obs.s = obs.loc$x, obs.t = obs.loc$t)
