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