Signal Toolkit - zp2ss

Function File: [a, b, c, d] = zp2ss (z, p, k)

Conversion from zero / pole to state space.

Inputs

z

p

Vectors of (possibly) complex poles and zeros of a transfer function. Complex values must come in conjugate pairs (i.e., x+jy in z means that x-jy is also in z).

k

Real scalar (leading coefficient).

Outputs

a

b

c

d

The state space system, in the form:

      .
      x = Ax + Bu
      y = Cx + Du
