Struct Projection 

pub struct Projection {
    pub source_pop: usize,
    pub target_pop: usize,
    /* private fields */
}

Fields

source_pop: usize

Source population index

target_pop: usize

Target population index

Implementations

impl Projection

pub fn new<R: Rng>( source_pop: usize, target_pop: usize, source_size: usize, target_size: usize, pattern: &ConnectionPattern, synapse_template: &Synapse, weight_init: WeightInit, delay_init: DelayInit, rng: &mut R, ) -> Result<Self>

Create a new projection with specified connection pattern.

Arguments

• source_pop - Source population index
• target_pop - Target population index
• source_size - Number of neurons in source population
• target_size - Number of neurons in target population
• pattern - Connection pattern
• synapse_template - Template synapse (will be cloned for each connection)
• weight_init - Weight initialization scheme
• delay_init - Delay initialization scheme
• rng - Random number generator

pub fn all_to_all<R: Rng>( source_pop: usize, target_pop: usize, source_size: usize, target_size: usize, synapse_template: &Synapse, weight: f64, delay: f64, rng: &mut R, ) -> Result<Self>
