WebYou could do this simply by typing the following do loop. Do i=1,n a (i)= 1.0/a (i) End do This loop would work fine, except where an element of "a" originally was equal to zero. This would mean you were dividing by zero in the mathematical expression. To prevent this, the where statement can be used in the following manner. WebWhile in FORTRAN 90 the same loop can be written as do 100 i=1,1000 xarray(i)=indata(i)*a k = k+1 if (xarray(i).eq.0.or.k.eq.kmax) then exit else if (i.gt.1) results(i)=xarray(i)+xarray(i-1) else results(i)=xarray(i) end if 100 continue
