SymmetricMatrix.condensed_form()[source]#

Return an array of distances in condensed format.

Returns:
datandarray

One-dimensional numpy.ndarray of values in condensed format.

Notes

Condensed format is described in [1].

The conversion is not a constant-time operation, though it should be relatively quick to perform.
