# Transport Functions¶

The transport functions $$J(n,x)$$ are defined by the integral representations $$J(n,x) := \int_0^x t^n e^t /(e^t - 1)^2 dt$$.

gsl_sf_transport_2(x)

This routine computes the transport function $$J(2,x)$$.

gsl_sf_transport_3(x)

This routine computes the transport function $$J(3,x)$$.

gsl_sf_transport_4(x)

This routine computes the transport function $$J(4,x)$$.

gsl_sf_transport_5(x)

This routine computes the transport function $$J(5,x)$$.
