The current matrix (including augmentation if it has been carried out) is scanned for the absolute and relative sizes of elements. The following information is reported:

• Largest and smallest elements in the matrix;
• Counts of the ranges of row ratios in powers of 10 (e.g. number of rows with ratio between 10 and 100);
• List of the rows (with largest and smallest elements) which appear in the highest range;
• Counts of the ranges of column ratios in powers of 10;
• List of the columns (with largest and smallest elements) which appear in the highest range;
• Element ranges in powers of 10.

Where any of the reported items (largest or smallest element in the matrix or any reported row or column element) is in a penalty error vector, the results are repeated, excluding all penalty error vectors.
