evaluate(sample)

Compute the MinDist criterion for a specific design.

Parameters:
designSample or 2-d array like

The design

Returns:
critfloat

The MinDist criterion

Examples

>>> import openturns as ot
>>> # Build an LHS using openturns class
>>> lhs = ot.LHSExperiment(ot.Uniform(), 100)
>>> design = lhs.generate()
>>> # Compute the MinDist criterion
>>> crit = ot.SpaceFillingMinDist().evaluate(design)
