The main interfaces of the Matrix assembly are:
IBasicMatrixAggregator - interface that contains properties that are used to set basic aggregation mechanism parameters.
IChronologicalMatrixAggregator - interface that contains properties that are used to set chronological aggregation mechanism parameters.
IMatrix - interface that contains properties and methods that are used to work with a data matrix.
IMatrixCoord - interface that contains properties and methods that are used to work with an element coordinate in a matrix.
