Sparse Matrix Data Structures

Data Representation

DataRepresentation
Dense	Unit-aware explicit dense matrix.

CSR / CSC (Compressed Sparse Row / Column)

CSR	Event-driven and Unit-aware Compressed Sparse Row (CSR) matrix.
CSC	Event-driven and Unit-aware Compressed Sparse Column (CSC) matrix.

JITC Base

JITCMatrix	Just-in-time Connectivity (JITC) matrix.
JITCScalarMatrix	Base class for Just-In-Time Connectivity Scalar-weight matrices.

JITC Scalar

JITCScalarR	Just-In-Time Connectivity Homogeneous matrix with Row-oriented representation.
JITCScalarC	Just-In-Time Connectivity Homogeneous matrix with Column-oriented representation.

JITC Normal

JITCNormalR	Just-In-Time Connectivity Normal distribution matrix with Row-oriented representation.
JITCNormalC	Just-In-Time Connectivity Normal distribution matrix with Column-oriented representation.

JITC Uniform

JITCUniformR	Just-In-Time Connectivity matrix with Row-oriented representation for uniform weight distributions.
JITCUniformC	Just-In-Time Connectivity matrix with Column-oriented representation for uniform weight distributions.

Fixed Connectivity

FixedNumConn	Unified, layout-aware sparse matrix with a fixed number of connections.
FixedNumPerPre	Sparse matrix with a fixed number of post-synaptic connections per pre-synaptic neuron (row-major ELL; structurally equivalent to brainevent.CSR).
FixedNumPerPost	Sparse matrix with a fixed number of pre-synaptic connections per post-synaptic neuron (stores W^T row-major; structurally equivalent to brainevent.CSC).
