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
