Function: abcd2lfr

Purpose

Let abcd = [a b;c d] (lfr-object) with outputs [d/dt x; y] and inputs [x;u]. The function abcd2lfr transforms abcd to an lfr-object with output y and input u, i.e., the integrator block I/s or the delay block I/z are included in the matrix Delta.

Synopsis

• [sys] = abcd2lfr(abcd,nstates,cont)

Input arguments

abcd	LFR-object representing the matrix [a b;c d] of a LTI system
nstates	Number of states
cont	Continuous-time system: cont=1 (default) or discrete-time system: cont=0.

Output argument

sys	Corresponding input/output lfr-object.
