Method

NumCosmoMathFunctionSampleSetget_absmaxF_min

Declaration [src]

gdouble
ncm_function_sample_set_get_absmaxF_min (
  NcmFunctionSampleSet* fss
)

Description [src]

Computes the minimum of the maximum absolute values across all components: $$\min_{i=0}^{n-1} (\max_x |F_i(x)|)$$

This returns the smallest peak value among all components, which is useful for setting conservative tolerances that ensure even the weakest component is adequately resolved in adaptive refinement algorithms.

Return value

Type: gdouble

The minimum of the component-wise maximum absolute values, or GSL_POSINF if there are no components.
