[A, B, C, D, E] = compreal(numerator, denominator)
| Parameter | Description |
|---|---|
| numerator | a vector or matrix |
| denominator | a 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. |
| E (n x n) | matrix. |
[A, B, C, D, E] = compreal(numerator, denominator) calculates a state-space realization represented by matrices A, B, C, D, and E.
The E matrix is an empty matrix (identity matrix) when there are at least as many poles as zeros.
However, if there are more zeros than poles, the E matrix becomes singular.
numerator = [0 10 10];
