Determining optimal reordering of columns using Casorati matrix from a cardiac perfusion dataset. (a) Comparison of nuclear norms (i) without any reordering (labeled original norm) with (ii) reordering all columns in an ascending fashion (labeled all columns ascend) and with (iii) reordering only a random subset of columns in ascending fashion while the remaining columns reordered in descending fashion for 100 000 experiments. (b) Comparison of nuclear norms with different ascending/descending reordering combinations for real and imaginary parts to determine optimal reordering within each column.
