ncm_powspec_filter_eval_dnvar_dlnrn (
NcmPowspecFilter* psf,
const gdouble z,
const gdouble lnr,
guint n
)
Description [src]
Evaluates the derivatives of the filtered variance at lnr and z, namely:
- $n = 0 \rightarrow \sigma(r, z)^2$,
- $n = 1 \rightarrow \frac{\mathrm{d}\sigma^2}{\mathrm{d} \ln r}$,
- $n = 2 \rightarrow \frac{\mathrm{d}^2\sigma^2}{\mathrm{d}(\ln r)^2}$,
- $n = 3 \rightarrow \frac{\mathrm{d}^3\sigma^2}{\mathrm{d}(\ln r)^3}$.
