STProfileFrequencyAddresses
Calculate a frequency profile from a mapped spike train, for each address
Syntax
[vInstFrequency, vKey] = STProfileFrequencyAddresses(stMappedTrain, tTimeWindow)
Description
stTrain is a spike train containing a mapping.
tTimeWindow specifies the duration in seconds of the time bins that spikes
will be lumped into. STProfileFrequency will calculate the spike train frequency for each bin.
These frequencies will be returned in vInstFrequency. The format of each row will be
[time_stamp frequency1 frequency2 ...]. time_stamp is a real value representing the median time of each bin. frequencyN is the average frequency of a single neuron during each time bin, in Hz. Each row in vKey gives the address of the
neuron corresponding to one of the columns in vInstFrequency. For
example, vKey(1) is the address of the neuron corresponding to
frequency1 in vInstFrequency.
Note that STProfileFrequencyAddresses will skip neurons with no spikes
in stMappedTrain. Don't rely on the order of vKey being
monotonically increasing.
