Create a mode model from a C++ input file. This function will compile the mode support around your model and return an object that can be used to work with the model.
mode(filename, quiet = FALSE, workdir = NULL, skip_cache = FALSE)
mode(filename, quiet = FALSE, workdir = NULL, skip_cache = FALSE)
filename |
The path to a single C++ file |
quiet |
Logical, indicating if compilation messages from
|
workdir |
Optional working directory to use. If |
skip_cache |
Logical, indicating if the cache of previously
compiled models should be skipped. If |
A generator object based on your source files
Create a mode control object for controlling the adaptive stepper. The returned object can be passed into a mode model on initialisation.
mode_control( max_steps = NULL, atol = NULL, rtol = NULL, step_size_min = NULL, step_size_max = NULL, debug_record_step_times = NULL )
mode_control( max_steps = NULL, atol = NULL, rtol = NULL, step_size_min = NULL, step_size_max = NULL, debug_record_step_times = NULL )
max_steps |
Maxmimum number of steps to take. If the integration attempts to take more steps that this, it will throw an error, stopping the integration. |
atol |
The per-step absolute tolerance. |
rtol |
The per-step relative tolerance. The total accuracy will be less than this. |
step_size_min |
The minimum step size. The actual minimum
used will be the largest of the absolute value of this
|
step_size_max |
The largest step size. By default there is no maximum step size (Inf) so the solver can take as large a step as it wants to. If you have short-lived fluctuations in your rhs that the solver may skip over by accident, then specify a smaller maximum step size here. |
debug_record_step_times |
Logical, indicating if we should record
the steps taken. This information will be available as part of
the |
