FNdat {magi} | R Documentation |
Dataset of noisy observations from the FitzHugh-Nagumo (FN) equations
Description
The classic FN equations model the spike potentials of neurons, where system components and
are the voltage and recovery variables, respectively.
and
are governed by the following differential equations:
where are system parameters.
This dataset was generated by first numerically solving these ODEs from
to
, with initial conditions
and
and parameters
.
The system components were taken to be measured at 28 observation time points (as indicated in
time
column) with additive Gaussian noise (standard deviation 0.2).
Usage

Format
A data frame with 28 rows and 3 columns (time, ,
).
