conatus.expert.ir_system(problem, parameters, *, values=None, dp_fd=None, pointwise=None, ncc=None)[source]

DynamicalSystem of an IR IVP with free parameters parameters.

values fixes the starting values (default: the values declared on the Parameters; a Parameter without value must be given here). The IVP is discretized once (plus one plan per Laurent sample if a free parameter enters an LHS). pointwise (0-D systems only): compile the IR expressions to numpy; None = automatic (True when every basis holds one mode), declared by explain(). dp_fd: central FD step in p, required only if a free parameter enters non-polynomially.

Parameters:

  • parameters (Sequence[str | Parameter])

  • values (Mapping[str, float] | None)

  • dp_fd (float | None)

  • pointwise (bool | None)

  • ncc (Mapping | None)

Return type:

DynamicalSystem
