SSM_PO2SN
This function performs continuation of saddle-node (SN) periodic orbits of slow dynamics. Each periodic orbit corresponds to a torus (quasi-periodic) response in regular time dynamics. The continuation here starts from a saved SN solution.
FRCIRS = SSM_PO2SN(OBJ,OID,RUN,LAB,PARRANGE,OUTDOF,VARARGIN)
oid: runid of current continuation
-
run: runid of continuation for saved solution
-
lab: label of continuation for saved solution, which must be the label of a saddle-node point
-
parRange: continuation domain of parameters. It is of the form {[om1,om2],[f1,f2]}, where [om1,om2] and [f1,f2] specify the continuation domain of excitation frequency and amplitude respectively. You can give empty array and then no domain is specified, e.g., {[],[f1,f2]} only presents the domain of forcing amplitude
outdof: output for dof in physical domain
-
varargin: ['saveICs'] flag for saving the initial point in trajectory
