rlist

Scilab rational fraction function definition

Syntax

[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 , and on the other, to use some functions as , 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
