//! \brief
//! Delayed 'maximum values' operation.
//! The dimension, along which the maxima are found, is set via 'dim'.
//! For dim = 0, the maximum value of each column is found (i.e. searches by traversing across rows).
//! For dim = 1, the maximum value of each row is found (i.e. searches by traversing across columns).
//! The default is dim = 0.
