Class MddLocalMatrix

java.lang.Object
jline.api.mdd.MddLocalMatrix
public class MddLocalMatrix extends Object
A local rate matrix W_k^e of the Kronecker descriptor, held row-compressed.

The aggregation only ever walks a row of W and needs its row sums (the local enabling rates lambda_k^e), so the rows are stored as parallel column/value arrays rather than as a general sparse matrix. Duplicate triplets are summed when the matrix is built, so a caller may emit the same (i,j) more than once.
