Type Members

1. class 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].
