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