9 #S1| | | s1(i,j)=a(i,j)s4(j,i)**2 manual for more details). The original #
10 # | | else program is given on the left. For each #
11 #S2| | | s1(i,j)=s1(i,j-1)-s4(j,i)**2 statement the original schedule is: #

13 #S3| | s2(i)=sqrt(a(i,i)) T_S2(i,j) =(i,0,j,1,0,0) #
14 # | else T_S3(i) =(i,1,0,0,0,0) #
15 #S4| | s2(i)=sqrt (s1(i,i-1)) T_S4(i) =(i,2,0,0,0,0) #
