If you want to use the control package instead, you can do the following: octave:1> sysc = tf ([1, 0], [1, 1.4e6]) Transfer function 'sysc' from input 'u1' to output ... s y1: ----------- s + 1.4e+06 Continuous-time model. octave:2> sysd = c2d (sysc, 1e-6, "bilin") Transfer function 'sysd' from input 'u1' to output ... 0.5882 z - 0.5882 y1: ----------------- z - 0.1765 Sampling time: 1e-06 s Discrete-time model. octave:3> Lukas ------------------------------------------------------------------------------ Ridiculously easy VDI.
