hi,
this is the equation I was able to write in Matlab
AF = (z-z1)*(z-z2)*(z-z3) -------------- (1)
where I calculated the values of z1, z2 and z3 using my program
as z1 = j, z2 = 1 and z3 = -j .-----------(2)
from this I have to form the equation in the following format as
AF = z^3-z^2+z-1 -------------(3)
and to write the coefficients of the equation as
a1 = -1 ,a2 = 1, a3 = -1 and a4 = 1 ----------(4)
can anybody help me how to proceed further
to form equation (3) and (4) in matlab
