Class inte_qagil_gsl (o2scl)¶

template<class func_t = funct>
class o2scl::inte_qagil_gsl : public o2scl::inte_transform_gsl<funct>¶ Integrate a function over the interval \( (-\infty, b] \) (GSL)
The integral on the unbounded interval is rewritten over the semi-open interval \( (0, 1] \) via a variable transformation,
\[ \int_{-\infty}^b f(x)~dx = \int_0^1 f\left[b - (1-t)/t\right]t^{-2}~dt, \]and the right hand side is evaluated with o2scl::inte_qags_gsl.See GSL-based integration details in the User’s guide for general information about the GSL integration classes.
