For certain applications, a transfer function representation of the linearized system may be more desirable than a statespace representation. Analyze > Transfer Function Info presents a linearized system in transfer function form and includes the following information:
• The numerator and denominator polynomials are presented in powers of the complex variable s defined as:
where
• The gain of the transfer function
• The factors of the numerator (zeros) and the denominator (poles). The zeros and poles may appear in the following format:
(realpart, imaginarypart)
The transfer function is computed from the statespace matrices using a similarity transformation. The poles and zeros are computed by converting the numerator and denominator polynomials to square matrices and computing the corresponding eigenvalues.


If numerical roundoff errors occur during the factoring process, they can be corrected by using Analyze > Preferences.
To generate a linear transfer function
1. Prepare the system for linearization.
2. Choose Analyze > Transfer Function Info.
3. Resize or zoom in on the plot for better viewing.
