# tf2zp

Transforms (continuous) transfer function parameters to zero-pole-gain parameters.

## Syntax

[Z, P, K] = tf2zp(NUM, DEN)

## Inputs

`NUM`- The numerator polynomial coefficients.
`DEN`- The denominator polynomial coefficients.

## Outputs

- Z
- The zeros of the system.
- P
- The poles of the system.
- K
- The gain factors of the system.

## Example

```
num = [3 2];
den = [5 2.4 3];
[z, p, k] = tf2zp(num, den)
```

`z = -0.666666667
p = [Matrix] 2 x 1
-0.24000 + 0.73648i
-0.24000 - 0.73648i
k = 0.6`

## Comments

The function returns the zero-pole-gain parameters of a continuous-time transfer function.

Only SISO system representation is supported with this algorithm.
