inv(G) Scilab Function inv(G)
NAME
inv - matrix inverse
CALLING SEQUENCE
inv(X)
PARAMETERS
X : real or complex square matrix, polynomial matrix, rational matrix in
transfer or state-space representation.
DESCRIPTION
inv(X) is the inverse of the square matrix X. A warning message is printed
if X is badly scaled or nearly singular.
For polynomial matrices or rational matrices in transfer representation,
inv(X) is equivalent to invr(X).
For linear systems in state-space representation (syslin list), invr(X) is
equivalent to invsyslin(X).
EXAMPLE
A=rand(3,3);inv(A)*A
//
x=poly(0,'x');
A=[x,1,x;x^2,2,1+x;1,2,3];inv(A)*A
//
A=[1/x,2;2+x,2/(1+x)]
inv(A)*A
//
A=ssrand(2,2,3);
W=inv(A)*A
clean(ss2tf(W))
