inhomogeneous_poisson_generator


Name:
inhomogeneous_poisson_generator - provides Poisson spike trains  
at a piecewise constant rate
Examples:
 
The rate can be altered in the following way:
/inhomogeneous_poisson_generator Create /sc Set
sc << /rate_times [0.2 0.5] /rate_values [2.0 4.0] >> SetStatus

The average firing rate of each realization of the Poisson process will be
0.0 in the time interval [0, 0.2), 2.0 in the interval [0.2, 0.5)
and 4.0 from then on.

Description:
 
The inhomogeneous Poisson generator provides Poisson spike trains at a
piecewise constant rate to the connected node(s). The rate of the process
is changed at the specified times. The unit of the instantaneous rate
is spikes/s. By default, each target of the generator will receive
a different spike train.

Parameters:
 
The following parameters can be set in the status dictionary:
rate_times list of doubles - Times at which rate changes in ms
rate_values list of doubles - Rate of Poisson spike train in spikes/s
allow_offgrid_times bool - If false, spike times will be rounded to the
nearest step if they are less than tic/2 from
the step, otherwise NEST reports an error.
If true, spike times are rounded to the
nearest step if within tic/2 from the step,
otherwise they are rounded up to the *end*
of the step. Default: false

Receives:
DataLoggingRequest  

Sends:
SpikeEvent
