Method as_matrix

src/datasets.rs:319–334

Returns a matrix which contains the population consisting of one or more subpopulations. Each row of the matrix represents a sample generated from one of the subpopulations. The value in the first column of a row denotes the subpopulation from which this sample has been generated. If the value is 0 this sample has been created from the first subpopulation (i.e. the first data source that has bee
