Multi-domain sampler integration — fm_int_multi

Combine integration over different domains

Usage

fm_int_multi_sampler(domain, samplers, ..., extra = NULL)

Arguments

domain: A list of named domains
samplers: A named list of samplers
...: Passed on to each fm_int() call.
extra: Optional character vector with names of variables other than the integration domains to be included from the samplers. If NULL (default), all additional variables are included.

Value

An object with integration points and weights

Examples

fm_int_multi_sampler(
  domain = list(x = fm_mesh_1d(1:4), y = 11:12),
  samplers = tibble::tibble(
    x = rbind(c(1, 3), c(2, 4)),
    y = c(12, 11)
  )
)
