generate.1d.mesh: Create 1d mesh from observation locations.

In davidbolin/ngme: Linear Mixed Effects Models With Flexible Distributions

Create 1d mesh from observation locations.

Description

A function to create mesh for 1d FEM discretization.

Usage

generate.1d.mesh(
  x,
  max.dist,
  cutoff = 1e-10,
  extend = NULL,
  Y = NULL,
  loc.Y = NULL,
  max.dY = -1,
  nJump = 3,
  fix.differences = TRUE
)

Arguments

x	A list of measurement locations.
max.dist	The largest distance between nodes in the mesh
cutoff	Merge nodes in x that are closer than cutoff

Details

This is a supplementary function to be used internally by other functions.

Value

Returns a list with mesh nodes, distances, and number of nodes.
