Method parfrac/parfrac
PARFRAC partial fraction representation of a transfer function.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
DESCRIPTION: PARFRAC partial fraction representation of a transfer function.
R(1) R(2) R(n)
H(s) = -------- + -------- + ... + -------- + K(s)
s - P(1) s - P(2) s - P(n)
SUPER CLASSES: ltpda_tf < ltpda_uoh < ltpda_uo < ltpda_obj
CONSTRUCTOR:
r = parfrac() - creates an empty parfrac object
r = parfrac(res, poles, dir) - construct from residuals, poles
and direct terms
r = parfrac(..., 'name') - construct including name
r = parfrac(..., iunits, ounits) - include input and output units
r = parfrac(pl) - create a parfrac object from the
description given in the parameter list.
r = parfrac(pzm) - create a parfrac from a pzmodel.
r = parfrac(rat) - create a parfrac from a rational TF.
The poles can be specified in a array or a cell as a real or complex number.
Example: r = parfrac([1 2+1i 2-1i], [6 1+3i 1-3i], []);
