tangent - linearization of a dynamical system at an equilibrium point
Calling Sequence
- [f,g,newm]=tangent(ff,xe,[ue])
Parameters
-
ff: a string which gives the name of the Scilab macro which codes the system
-
xe: column vector which gives the equilibrium point for the value ue of the parameter
-
ue: real value.
-
f, g: two matrices for the linearised system dxdot=f.dx + g.du
-
newm: A new macro of type [y]=newm(t,x,u) which computes the field of the linearised system (newm(t,xe,ue)=0)
Description
linearises around the equilibrium point (xe,ue) the vector field of
the dynamical system given by a Scilab macro ff, xdot=ff(t,x,[u]).
The dynamical system is supposed to be autonomous.
