If you put pracma in "Numerical Analysis and Linear Algebra", then I feel you should also include  BB and nleqslv under that heading. Both of these do things that can be classified as Numerical Analysis. And both can of course also be used for simulation.

BB  solve  (sparse) systems of non linear equations using spectral gradient methods
nleqslv solve systems of nonlinear equations combining global strategies with a Broyden or Newron method.
