Function File: [out,niter] = tst_theta_method (cirstruct,x,t,tol,maxit,theta,pltvars,verbosity);

Perform a transient simulation of the system described by cirstruct over the time interval t using the theta-method with parameter theta.

The initial value for the state vector is computed by solving a steady state problem at t(1), with starting guess x.

tol and maxit are parameters passed to nls_newton_raphson.

The output out will contain the value of the state vector at each point of t.

The optional parameter verbosity controls the amount of output produced:

  • - if verbosity(1) != 0, information on the progress of the algorithm are output at runtime
  • - if verbosity(2) != 0, the plot of the variables whose names are listed in pltvars is produced after the computation

The optional output niter returns the number of Newton iterations needed to reach convergence.
