Description

Low level function for computing finite element matrices, spherical harmonics, B-splines, and point mappings with barycentric triangle coordinates.

Usage

inla.fmesher.smorg(loc, tv,
                   fem = NULL, aniso = NULL,
                   gradients = FALSE,
                   sph0 = NULL, sph = NULL, bspline = NULL,
                   points2mesh = NULL,
                   splitlines = NULL,
                   output = NULL,
                   keep = FALSE)

Arguments

loc	3-column triangle vertex coordinate matrix.
tv	3-column triangle vertex index matrix.
fem	Maximum finite element matrix order to be computed.
aniso	A two-element list with gamma and v for an anisotropic operator div H grad, where H = gamma I + v v'
gradients	When TRUE, calculate derivative operator matrices dx, dy, and dz.
sph0	Maximal order of rotationally invariant spherical harmonics.
sph	Maximal order of general spherical harmonics.
bspline	Rotationally invariant B-splines on a sphere. 3-vector with number of basis functions n, basis degree degree, and a logical; TRUE uniform knot angles, FALSE for uniform spacing in sin(latitude).
points2mesh	3-column matrix with points to be located in the mesh.
splitlines	A list with elements loc (3-column coordinate matrix) and idx (2-column index matrix) describing line segments that are to be split into sub-segments at triangle boundaries.
output	Names of objects to be included in the output, if different from defaults.
keep	When TRUE, for debugging purposes keep the fmesher I/O files on disk.

Value

A list of generated named quantities.
