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).
