rlist

Scilab rational fraction function definition

Calling Sequence

[r] = rlist()
[r] = rlist(N, D [,dom])

Arguments

N,D

polynomial martices.

dom

character string, or [] or a scalar.

r

tlist ("r" list) representing the rational fraction.

Description

rlist(N, D, dom) is a shortcut to tlist(['r','num','den','dt'], N, D, dom).

To correspond to the domain time of a linear system, dom must be equal to 'c','d', [] or a scalar. One the one hand, to be similar to functions as syslin, and on the other, to use some functions as tf2ss, it is necessary that dom is equal to these values.

Examples

s=poly(0,'s');
W=[1/s,1/(s+1)]
W'*W
Num=[s,s+2;1,s];
Den=[s*s,s;s,s*s];
rlist(Num,Den,[])

H1=(1+2*s)/s^2;
S1bis=syslin('c',H1)
r=rlist(H1.num, H1.den, 'c')
r == S1bis
