DenseMatrix extends Matrix
Column-major dense matrix.
Column-major dense matrix. The entry values are stored in a single array of doubles with columns listed in sequence. For example, the following matrix
1.0 2.0 3.0 4.0 5.0 6.0
is stored as
[1.0, 3.0, 5.0, 2.0, 4.0, 6.0]

is stored as
values: [1.0, 2.0, 3.0, 4.0, 5.0, 6.0]
,rowIndices=[0, 2, 1, 0, 1, 2]
,colPointers=[0, 2, 3, 6]
