Method

NumCosmoHICosmoVexpx_y

Declaration [src]

void
nc_hicosmo_Vexp_x_y (
  NcHICosmoVexp* Vexp,
  const gdouble tau,
  gdouble* x,
  gdouble* y
)

Description [src]

Computes the phase space variables $x(\tau)$ and $y(\tau)$ at time $\tau$, where $x = \dot{\phi} / (\sqrt{6} H)$, $y = \sqrt{1 - x^2}$, and $a = a_b \exp(\tau^2/2)$.

Parameters

tau

Type: const gdouble

$\tau$.

x

Type: gdouble*

The value of $x(\tau)$.

The argument will be set by the function.
y

Type: gdouble*

The value of $y(\tau)$.

The argument will be set by the function.
