Mixed precision chart

Caption

Journey from global dense double precision representation of a covariance matrix (left) to a hybrid compressed representation that ushers in a renaissance of numerical linear algebra with a tunable level of accuracy (right) through adaptive rank reduction (top) and adaptive precision reduction (bottom). Only lower triangle shown due to symmetry.
