The number of first-order ordinary differential equations solved by the integration function. It must be the same argument supplied to the setup function
ivp_adams_setup()and the integration functions
- commdict, communication object
- ypfloat, ndarray, shape
The approximate derivative of the solution component , as supplied in on output from the integration function at the output value of . These values are obtained by the evaluation of except when the output value of the argument in the call to the integration function is and , in which case they are obtained by interpolation.
The value of the independent variable which the integrator has actually reached. will always be at least as far as the output value of the argument (from the integration function) in the direction of integration, but may be further.
The last successful step size used by the integrator.
The next step size which the integration function would attempt.
The order of the method last used (successfully) by the integration function.
The order of the method which the integration function would attempt on the next step.
The number of steps attempted by the integration function that have been successful since the start of the current problem.
The number of steps attempted by the integration function that have failed since the start of the current problem.
A tolerance scale factor, , returned when the integration function exits with = 3. If and are uniformly scaled up by a factor of and
ivp_adams_setup()is called, the next call to the integration function is deemed likely to succeed.
If the integration function returned with = 4, specifies the index of the component which forced the error exit. Otherwise is .
