pde2path 2.3 switches, numerical constants and settings in the problem structure 'p'
The data in a pde2path structure p is organized as follows. Most values for stationary problems are initialized to standard values via stanparam, while p.hopf is initialized via hostanparam
- fuha: Function handles, e.g., p.fuha.outfu=@stanbra (default setting), p.fuha.G=.. (user defined)
- sw: switches such as sw.bifcheck
- nc: numerical controls, e.g., nc.tol, ...
- plot: switches and controls for plotting
- sol: values/fields calculated at runtime
- np,nu: #gridpoints, #PDE-unknowns
- u,tau: current solution and tangent
- branch: current branch data
- usrlam: target values for output
- file: filenames, switches, counters for file output
- mat: FEM matrices, such as M (always), K (for p.sw.sfem=+-1), drop, fill (for pBC)
- hopf: Hopf data, typically initialized via hoswibra
- mesh (see also pdeo): mesh-data for sfem=0,1;
- pdeo: mesh data for sfem for sfem=-1
- bel: bel-parameters
- ilup: parameters for iterative solvers
