STFilterDamping#

The damping type used to build the filter.

Synopsis#

typedef enum { ST_FILTER_DAMPING_NONE,
               ST_FILTER_DAMPING_JACKSON,
               ST_FILTER_DAMPING_LANCZOS,
               ST_FILTER_DAMPING_FEJER } STFilterDamping;

Values#

Notes#

The default is no damping.

For the definition of the damping coefficients, see for instance [Pieper et al., 2016]
