[A, B, C, D] = tf2ss(b, a)
| Parameter | Description |
|---|---|
| b | Transfer function numerator coefficients: vector or matrix. |
| a | Transfer function denominator coefficients: vector. |
| Parameter | Description |
|---|---|
| A (n x n) | Represents the system's state-transition matrix. It describes how the system's internal state evolves over time. |
| B (n x m) | Describes the input-to-state mapping. It shows how control inputs affect the change in the system's state. |
| C (p x n) | Represents the state-to-output mapping. It shows how the system's state variables are related to the system's outputs. |
| D (p x m) | Describes the direct feedthrough from inputs to outputs. In many systems, this matrix is zero because there is no direct feedthrough. |
[A, B, C, D] = tf2ss(b, a) transforms a single-input transfer function, either continuous-time or discrete-time, into an equivalent state-space representation.
