Wrapper for Dopri853 integrator.

Uses C target language only for functional specifications.

AuxVars(self, t, xdict, pdict=None, asarray=True)

source code

asarray is an unused, dummy argument for compatibility with Model.AuxVars

Overrides: ODEsystem'.ODEsystem.AuxVars

Jacobian(self, t, xdict, pdict=None, asarray=True)

source code

asarray is an unused, dummy argument for compatibility with Model.Jacobian

Overrides: ODEsystem'.ODEsystem.Jacobian

JacobianP(self, t, xdict, pdict=None, asarray=True)

source code

asarray is an unused, dummy argument for compatibility with Model.JacobianP

Overrides: ODEsystem'.ODEsystem.JacobianP

Rhs(self, t, xdict, pdict=None, asarray=True)

source code

asarray is an unused, dummy argument for compatibility with Model.Rhs

Overrides: ODEsystem'.ODEsystem.Rhs

del(self)
(Destructor)

source code

Overrides: baseclasses.Generator.__del__

init(self, kw)
(Constructor)

source code

Use the nobuild key to postpone building of the library, e.g. in order to provide additional build options to makeLibSource and compileLib methods or to make changes to the C code by hand. No build options can be specified otherwise.

Overrides: object.__init__

compileLib(self, libsources=`[]`, libdirs=`[]`)

source code

compileLib generates a python extension DLL with integrator and vector
field compiled and linked.

libsources list allows additional library sources to be linked.
libdirs list allows additional directories to be searched for
  precompiled libraries.

compute(self, trajname, dirn=`'f'`, ics=None)

source code

This is an abstract class.

Overrides: ODEsystem'.ODEsystem.compute: (inherited documentation)

forceLibRefresh(self)

source code

forceLibRefresh should be called after event contents are changed, or alterations are made to the right-hand side of the ODEs.

Currently this function does NOT work!

makeLib(self, libsources=`[]`, libdirs=`[]`, include=`[]`)

source code

makeLib calls makeLibSource and then the compileLib method. To postpone compilation of the source to a DLL, call makelibsource() separately.

makeLibSource(self, include=`[]`)

source code

makeLibSource generates the C source for the vector field specification. It should be called only once per vector field.

_paraminfo

Value:

{'atol': 'Absolute error tolerance.',
 'beta': 'The "beta" for stabilized step size control. Larger values f
or beta ( <= 0.1 ) make the step size control more stable. Negative in
itial value provoke beta=0; default beta=0.04',
 'boundsCheckMaxSteps': 'Last step to bounds check if checkBound==1. D
efaults to 1000.',
 'checkBounds': 'Switch to check variable bounds: 0 = no check, 1 = ch
