Function

NumCosmoMathintegral_cached_x_inf

Declaration [src]

gint
ncm_integral_cached_x_inf (
  NcmFunctionCache* cache,
  gint* F,
  gdouble x,
  gdouble* result,
  gdouble* error
)

Description [src]

This function searchs for the nearest x_near value previously chosed as the lower integration limit and perform the integration at $[x, x_{near}]$ interval. This result is summed to that obtained at $[x_{near}, \infty]$ and then it is saved in the cache.

This function is not directly available to language bindings.
