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
