Description

EVALDVAR Evaluates a dependent variable in a point on a group of cells.

[ VDVARVAL ] = EVALDVAR( SFUN, I_EVAL, N_SDIM, N_VERT, XI, AINVJAC, DOFMAP, U ) Evaluates a dependent variable in point XI on the cells given in dofmap. SFUN specifies which shape function to use with the corresponding solution vector U.
