Examples

Create a symmetric matrix in condensed form and expand to square form:

>>> from skbio.stats.distance import SymmetricMatrix
>>> sm = SymmetricMatrix([1, 2, 3], ids=['a', 'b', 'c'], condensed=True)
>>> sm.data
array([ 1., 2., 3.])
>>> sm.redundant_form()
array([[ 0., 1., 2.],
       [ 1., 0., 3.],
       [ 2., 3., 0.]])
