View source for One-first Procedure

The '''One-first Procedure''' is performed when the [[One-first Selection Rule]] is chosen.

Firstly, it resets:
m<sub>pq</sub>, (p, q) Є X1 to one and then 
if X0 is not empty it resets m<sub>pq</sub>, (p,q) Є X0 to zero. 

If the developer desires to change more than one element or entry in the matrix, he/she can apply the above correction procedure iteratively.
