... values can be real numbers, symbols, or user defined symbolic expressions.
Frequency domain results can be transformed to time domain via Inverse Laplace or Z Transform.
Transformation between S-domain and Z-domain results can be done via Forward or Backward Derivatives (Euler Transform), Bilinear, or Impulse Invariant Transforms.
Provide Bode, Gain-Phase, Nyquist, Pole-zero, Impulse, and Step response plots. Plot ranges can be set manually or automatically.
