Description

EVALSFUN Shape function evaluation driver subroutine.

[ VBASE, NLDOF, XLDOF, SFUN ] = EVALSFUN( SFUN, I_EVAL, N_SDIM, N_VERT, I_DOF, XI, AINVJAC, VBASE ) Evaluates local basis function I_DOF in point XI for shape function SFUN on all cells corresponding to AINVJAC. Returns the evaluated values in VBASE and the local number of degrees of freedom on vertices, edges, faces, and cell interiors in NLDOF and XLDOF as well as the low level function name in SFUN.
