Equations may also make use of the row and column totals in either the (current) internal matrix or any of the external .ufm files. Thus the equation:
would imply that each new cell element equals the product of the row and column totals of the first input .ufm file divided by its current internal matrix value.
Syntax rules are that either ROW or ROW(0) implies the row total from the internal matrix. ROW(n) is the total from the n’th .ufm input matrix. Ditto COL, COL(0) and COL(n).
