__init__(*args)
evaluate(sample)

Compute the MinDist criterion for a specific design.

Parameters:

design : Sample or 2-d array like

The design

Returns:

crit : float

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)
getClassName()

hasName()

Test if the object is named.

Returns:

hasName : bool

True if the name is not empty.

hasVisibleName()

Test if the object has a distinguishable name.

Returns:

hasVisibleName : bool
