Class inte_multi (o2scl)¶
-
template<class func_t = multi_funct, class vec_t = boost::numeric::ublas::vector<double>>
class o2scl::inte_multi¶ Multi-dimensional integration over a hypercube [abstract base].
Multi-dimensional integration over a region defined by constant limits. For more general regions of integration, use children of the class inte_gen.
Public Functions
-
inline inte_multi()¶
-
inline virtual ~inte_multi()¶
-
inline virtual double minteg(func_t &func, size_t ndim, const vec_t &a, const vec_t &b)¶
Integrate function
func
over the hypercube from \( x_i=a_i \) to \( x_i=b_i \) for \( 0<i< \) ndim-1.
-
virtual int minteg_err(func_t &func, size_t ndim, const vec_t &a, const vec_t &b, double &res, double &err) = 0¶
Integrate function
func
over the hypercube from \( x_i=a_i \) to \( x_i=b_i \) for \( 0<i< \) ndim-1.
-
inline double get_error()¶
Return the error in the result from the last call to minteg() or minteg_err()
This will quietly return zero if no integrations have been performed.
-
inline const char *type()¶
Return string denoting type (“inte_multi”)
Public Members
-
bool err_nonconv¶
If true, call the error handler if the routine does not “converge”.
-
int verbose¶
Verbosity.
-
double tol_rel¶
The maximum “uncertainty” in the value of the integral (default \( 10^{-8} \)).
Protected Attributes
-
double interror¶
The uncertainty for the last integration computation.
