Noob question about using MATLAB

  1. Apr 5, 2010 #1
    so, i have this little problem

    can anyone tell me to put this transfer function in matlab?

    T(s)=(s^4 + 2s^3 -13s^2 -38 -24)/(s(s^4 + 6s^3 -5s^2 -42s + 40))

    i really new to matlab:cry:

    If you want to use Matlabs transfer function capabilities (step(), etc.):

    >> T = tf([1,2,-13,0,-38-24],[1,6,-5,-42,14,0])

    this is for a contuninuous time transfer finction like the one you showed, it is slightly different for DT.

    >> help tf
