EVALEXPRDOF Evaluates an expression in the degrees of freedom.
[ VEVAL, IND_DOF ] = EVALEXPRDOF( EXPR, DVAR_OR_SFUN, PROB, IND_B ) Given a valid PROB struct evaluates the expression(s) EXPR in the degrees of freedom corresponding to dependent variable DVAR (or shape function SFUN). IND_B indicates evaluation for selected boundaries (no argument evaluates for all dofs).
Input Value Description
-----------------------------------------------------------------------------------
expr string (cell array) String expression(s) to evaluate
dvar/sfun scalar (or string) Index to dvar or sfun string expression
prob struct Problem definition struct
ind_b integers (Optional) evaluation boundaries
.
Output Value/(Size) Description
-----------------------------------------------------------------------------------
vEval [n_dof,n_expr] Output vector/array of evaluated values
ind_dof [n_dof,1] Dof numbering for evaluated values
