Method

NumCosmoMathFunctionSampleSetget_absmaxF_l2_norm

Declaration [src]

gdouble
ncm_function_sample_set_get_absmaxF_l2_norm (
  NcmFunctionSampleSet* fss
)

Description [src]

Computes the $L_2$ norm (Euclidean norm) of the maximum absolute values across all components: $$|\vec{F}|2 = \sqrt{\sum{i=0}^{n-1} (\max_x |F_i(x)|)^2}$$

This is useful for determining a reference scale when all components should contribute equally to error estimation.

Return value

Type: gdouble

The $L_2$ norm of the component-wise maximum absolute values.
