INTSUBD Integate expression over subdomains.

[ VAL ] = INTSUBD( S_EXPR, PROB, IND_S, IND_C, I_CUB, SOLNUM ) Integrates the expression S_EXPR over the subdomains indicated in IND_S, or alternatively the cells in IND_C. 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_s       [1,n_subd]             Subdomain numbers (default all)
ind_c       [1,n_cells]            Cell indices (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
