### Other Relevant Matlab Functions

Related Signal Processing Toolbox functions include

`tf2sos`-- Convert digital filter transfer function parameters to second-order sections form. (See §9.2.)`sos2ss`-- Convert second-order filter sections to state-space form.^{G.8}`tf2zp`-- Convert transfer-function filter parameters to zero-pole-gain form.`ss2zp`-- Convert state-space model to zeros, poles, and a gain.`zp2ss`-- Convert zero-pole-gain filter parameters to state-space form.

In Matlab, say `lookfor state-space` to find your state-space
support utilities (there are many more than listed above). In Octave,
say `help -i ss2tf` and keep reading for more functions (the
above list is complete, as of this writing).
