- class ConvolvedSpikeTrain
A class representing a single-unit spike train for which several helper vectors relating to a Van Rossum-like exponential convolution have been calculated.
Public Functions
- ConvolvedSpikeTrain()
Default constructor.
- ConvolvedSpikeTrain(std::vector< double > spikes, double tau)
Constructor accepting a spike train.
- Parameters
- spikes -
A vector of spike times.
- tau -
Time scale for the exponential kernel. There is a limit to how small tau can be compared to the absolute value of the spike times. An exception will be raised if this limit is exceeded; its value is system-dependent, but as a rule of thumb tau and the spike times should be within 4 orders of magnitude of each other.
- spikes -
- void distance(std::vector< std::vector< ConvolvedSpikeTrain > > & trains, double c, double ** d_matrix)
Compute the square (all-to-all) distance matrix for a set of multi-unit spike trains.
- Parameters
- trains -
The set of multi unit spike trains.
- c -
Cosine of the multi-unit mixing angle. c=0 corresponds to labelled-line code, c=1 to summed-population code.
- d_matrix -
The trains.size() x trains.size() matrix where the results will be written.
- trains -
- void distance(std::vector< std::vector< ConvolvedSpikeTrain > > & trains1, std::vector< std::vector< ConvolvedSpikeTrain > > & trains2, double c, double ** d_matrix)
Compute the rectangular (bipartite) distance matrix between two sets of multi-unit spike trains.
- Parameters
- trains1trains2 -
The sets of multi unit spike trains.
- c -
Cosine of the multi-unit mixing angle. c=0 corresponds to labelled-line code, c=1 to summed-population code.
- d_matrix -
The trains1.size() x trains2.size() matrix where the results will be written.

- void inner_product(std::vector< std::vector< ConvolvedSpikeTrain > > & trains, double c, double ** g_matrix)
Compute the square (all-to-all) inner product matrix for a set of multi-unit spike trains.
- Parameters
- trains -
The set of multi unit spike trains.
- c -
Cosine of the multi-unit mixing angle. c=0 corresponds to labelled-line code, c=1 to summed-population code.
- g_matrix -
The trains.size() x trains.size() matrix where the results will be written.
- trains -
- void inner_product(std::vector< std::vector< ConvolvedSpikeTrain > > & trains1, std::vector< std::vector< ConvolvedSpikeTrain > > & trains2, double c, double ** g_matrix)

- Parameters
- trains1trains2 -
The sets of multi unit spike trains.
- c -
Cosine of the multi-unit mixing angle. c=0 corresponds to labelled-line code, c=1 to summed-population code.
- g_matrix -
