Class mcovar_funct_rbf (o2scl)

O2scl : Class List

class mcovar_funct_rbf

Covariance function: 1D RBF with a noise term.

Note

There’s no point making a base class, since there aren’t really any virtual functions. The covariance functions have to be templates, to handle multiple vector types, so no virtual functions are allowed.

Public Functions

inline mcovar_funct_rbf()
