Using loops in quadratic equation

Find and state the nature of the roots of the quadratic equation y=ax^2+bx+c for 6 different set of {a,b,c}. . . . I already know how to go about with finding the nature and roots but how do i instruct matlab to go back to solve the second set after solving the first set {a,b,c} using for loops.

Thanks in advance for your time.

The image might not be so clear, but that's my flow chart...i get stuck where the decision "New Set" is made. How do i type that in my script?
