## Frequency Response

#### DESCRIPTION:

This function computes the frequency response of a system at given frequency points.
This function only applies to continuous-time system in current implementation.
The response at a specific frequency *w* is the value of transfer function at *s = jw*.
For a state-space model, the transfer function of the system (**A, B, C, D**) can be
obtained by following formula.

Please select a model to represent the system:
