Detailed Description

Simple implementation of the Synapses class. This class uses full matrix, so it is good for fully connected networks. If the connectivity of the network is less than 66%, you should use Sparse_synapses instead.

int aspi_basic_synapses_get_delay	(	aspi_object_t *	self,

	)

Return a synaptic delay between two synapses

Parameters:

	pre,:	presynaptic neuron (number)

double aspi_basic_synapses_get_trace	(	aspi_object_t *	self,
		int	pre,

Return a synaptic trace between two synapses

Parameters:

	post,:	postsynaptic neuron (number)

double aspi_basic_synapses_get_weight	(	aspi_object_t *	self,
		int	pre,
		int	post
	)

Return a synaptic weight between two synapses

Parameters:

	pre,:	presynaptic neuron (number)
	post,:	postsynaptic neuron (number)

Note that this can be implemented via sparse matrix, so doing for (i = 0; i <= N; i++) for (j = 0; j < N; j++) w = aspi_basic_synapses_get_weight (syn, i, j) ...

could be quite not good. Try

for (i = 0; i <= N; i++) { w = aspi_synapses_get_post_weight (syn, i); for (j = 0; j < aspi_synapses_get_post_size (syn, i); j++) ... }

aspi_object_t * aspi_basic_synapses_init	(	aspi_object_t *	self,
		int	n_neurons,
		double	trace_leak
	)

Basic synapses initializer

Parameters:

	self,:	already alloced synapses or NULL
	n_neurons,:	total number of neurons
	trace_leak,:	-XXX or 0 to disable leak, or a number between 0 and 1 to set trace leak. Behaviour is undetermined if number > 1

Note on delays: there are no delays by default. They are created if necessary. If delays stay to zero, delays matrices stay NULL.
