SIMP(G) Scilab Function SIMP(G)
NAME
simp - rational simplification
CALLING SEQUENCE
[N1,D1]=simp(N,D)
H1=simp(H)
PARAMETERS
N,D : real polynomials or real matrix polynomials
H : rational matrix (i.e matrix with entries n/d ,n and d real polynomi-
als)
DESCRIPTION
[n1,d1]=simp(n,d) calculates two polynomials n1 and d1 such that n1/d1 =
n/d.
If N and D are polynomial matrices the calculation is performed element-
wise.
H1=simp(H) is also valid (each entry of H is simplified in H1).
Caution:
-no threshold is given i.e. simp cannot forces a simplification.
-For linear dynamic systems which include integrator(s) simplification
changes the static gain. (H(0) for continuuous systems or H(1) for discrete
systems)
