| Parameter | Description |
|---|---|
| H | a lti model. |
| wIn | a cell {wmin, wmax} or a vector [wmin:wmax]. |
| lineSpec | Line style, marker, and color. |
| Parameter | Description |
|---|---|
| magnitude | Magnitude: size 1 x 1 x k (SISO). |
| phase | Phase: size 1 x 1 x k (SISO). |
| w | Frequencies: a vector: 1 x k. |
bode(sys) generates a Bode plot illustrating the frequency response of a dynamic system model, denoted as sys.
This plot visually represents the system's response in terms of both magnitude (measured in decibels, dB) and phase (measured in degrees) across varying frequencies.
The specific frequency points on the plot are automatically determined by bode based on the system's inherent dynamics.
