RATIONAL rational representation of a transfer function. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: RATIONAL rational representation of a transfer function. a(1)s^m + a(2)s^{m-1} + ... + a(m+1) H(s) = -------------------------------------- b(1)s^n + b(2)s^{n-1} + ... + b(n+1) CONSTRUCTOR: r = rational() - creates an empty rational object r = rational(nun, den) - construct from numerator and denominator coefficients r = rational(num, den, 'name') - construct including name r = rational(num, den, - construct from num, den, and io-units iunits, ounits) r = rational(pl) - create a rational object from the description given in the parameter list. r = rational(pzm) - convert the TF described by the pzmodel into a rational TF. Example constructor plists: Example: plist('filename', 'rational1.xml') Example: plist('filename', 'rational1.mat') Example: pzm = pzmodel(1, {1 2 3}, {4 5}) plist('pzmodel', pzm) Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
