DMPlexMetricIntersection#

Compute the intersection of a list of metrics

Synopsis#

#include "petscdmplex.h"   
PetscErrorCode DMPlexMetricIntersection(DM dm, PetscInt numMetrics, Vec metrics[], Vec metricInt)

Input Parameters#

  • dm - The DM

  • numMetrics - The number of metrics to be intersected

  • metrics - The metrics to be intersected

Output Parameter#

  • metricInt - The intersected metric

Notes#

The intersection of a list of metrics has the minimal ellipsoid which fits within the ellipsoids of the component metrics.

The implementation used here is only consistent with the minimal ellipsoid definition in the case numMetrics = 2.
