Spike times, in seconds.

n_shufflesint, optional, default: 1000

The number of shuffles to create.

start_timefloat, optional

The start time of the input spikes, used to set the time values of the shuffled outputs.

Returns:

shuffled_spikes2d array

Examples

Shuffle spike times using the ISI shuffle method:

>>> from spiketools.sim.times import sim_spiketimes
>>> spikes = sim_spiketimes(5, 30, 'poisson')
>>> shuffled_spikes = shuffle_isis(spikes, n_shuffles=5)
