Description

This object provides the computation of cosmological perturbations in a contracting universe with dark energy. It solves the equation of motion for the gauge invariant variable $\zeta$.

Functions

nc_de_cont_new ()

NcDECont *
nc_de_cont_new (const gdouble Omegaw,
                const gdouble OmegaL,
                const gdouble cs2,
                const gdouble w);

Creates a new NcDECont object.

Parameters

Omegaw

the value of $\Omega_w$

  

OmegaL

the value of $\Omega_\Lambda$

  

cs2

the value of $c_s^2$

  

w

the value of $w$

  

Returns

a new NcDECont.

[transfer full]

nc_de_cont_ref ()

NcDECont *
nc_de_cont_ref (NcDECont *dec);

Increase the reference of dec by one.

Parameters

dec

a NcDECont

  

Returns

dec .

[transfer full]

nc_de_cont_free ()

void
nc_de_cont_free (NcDECont *dec);

Decrease the reference count of dec by one.

Parameters

dec

a NcDECont

  

nc_de_cont_clear ()

void
nc_de_cont_clear (NcDECont **dec);

Decrease the reference count of dec by one, and sets the pointer *dec to NULL.

Parameters

dec

a NcDECont

  

nc_de_cont_set_k ()

void
nc_de_cont_set_k (NcDECont *dec,
                  const gdouble k);

Sets the value of $k$.

Parameters

dec

a NcDECont

  

k

the value of $k$

  

nc_de_cont_get_k ()

gdouble
nc_de_cont_get_k (NcDECont *dec);

Gets the value of $k$.

Parameters

dec

a NcDECont

  

Returns

the value of $k$.

Types and Values
