tf2zp SIMO transfer function to zero pole gain representation

## Syntax

    [z, p, k] = tf2zp(S)

## Arguments

S

  a single input transfer function.

z

  a matrix, the ith column contains the transmission zeros relative to the ith output.

p

  a column vector, the poles of the system

k

  a row vector, the ith element contains the gain relative to the ith output.

## Description

Converts a SIMO transfer function into zero pole gain representation.

## Examples

    H=syslin("d",[45.76+6*%z+2*%z^2;0.64*%z],[23.28+3.1*%z+%z^2;23.28+3.1*%z+%z^2])
    [z,p,k]=tf2zp(H)
