A pivot position in a matrix, A, is a position in the matrix that corresponds to a rowâleading 1 in the reduced row echelon form of A. Since the reduced row echelon form of A is unique, the pivot positions are uniquely determined and do not depend on whether or not row interchanges are performed in the reduction process. Also, the pivot of a row must appear to the right of the pivot in the above row in row echelon form.
Distribution pipes send water to the fire sprinkler heads using. a water source to maintain and increase water pressure according to design criteria.
