Function

NumCosmoMathintegral_cached_0_x

Declaration [src]

gint
ncm_integral_cached_0_x (
  NcmFunctionCache* cache,
  gint* F,
  gdouble x,
  gdouble* result,
  gdouble* error
)

Description [src]

This function searches for the nearest x_near value previously chosen as the upper integration limit and perform the integration at [x_near, x] interval. This result is summed to that obtained at [0, x_near] and then it is saved in the cache.

This function is not directly available to language bindings.
