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 evaulated values
