Functions

nc_cbe_clear

Instance methods

nc_cbe_calc_transfer

Gets whether it calculates the transfer function.

nc_cbe_compare_bg

Compares CLASS and NumCosmo background calculations and returns the worst discrepancy.

nc_cbe_free

Decreases the reference count of cbe.

nc_cbe_get_all_Cls

Gets and store the angular power spectra $C_l$’s calculated in the vectors TT_Cls, EE_Cls, BB_Cls and TE_Cls. If any of these vectors are NULL, then it is (they are) ignored.

nc_cbe_get_matter_ps

Gets the logarithm base e of the matter power spectrum as a function of the redshift $z$ and mode $\ln (k)$.
