INTBDR Integation of expression over boundaries.

[ VAL ] = INTSUBD( S_EXPR, PROB, IND_B, I_CUB, SOLNUM ) Integrates the expression S_EXPR over the boundaries indicated in IND_B. PROB is a valid finite element problem struct, and I_CUB specifies the numerical integration rule.

Input       Value/[Size]           Description
s_expr      string                 Expression to integrate
prob        struct                 Finite element problem struct
ind_b       [1,n_bdr]              Boundary numbers (default all)
i_cub       scalar                 Numerical integration rule (default 2)
solnum      scalar {n_sols}        Solution number/time to evaluate
Output      Value/[Size]           Description
val         scalar                 Result of integration
