Function: abcd2lfr

Purpose
Let a,b,c,d denote the state-space matrices of a standard LTI system representation. This function computes the input/output lfr-object corresponding to [a b;c d] given in lfr form. Converse lfr2abcd .

Synopsis

sys=abcd2lfr(abcd,nstates);

Input arguments

abcd LFR-object representing the matrix [a b;c d] of a LTI system (dx/dt = ax + bu, y = cx + du).
nstates Number of states

Output argument

sys Corresponding input/output lfr-object.

Example

   lfrs x y z
   A = [1+x x*y+z;0 x^2]; B = [1;y]; C=[y+z x*y]; D=1+y^2;
   S = [A B;C D];

   sys = abcd2lfr(S,2);
