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].

matrix entries in column major if not transposed or in row major otherwise
whether the matrix is transposed. If true, values stores the matrix in
row major.
Gets the (i, j)-th element.
Gets the (i, j)-th element.
Returns an iterator of column vectors.
Returns an iterator of column vectors. This operation could be expensive, depending on the underlying storage.
Returns a matrix in dense column major, dense row major, sparse row major, or sparse column major format, whichever uses less storage.
Returns a matrix in dense column major, dense row major, sparse row major, or sparse column major format, whichever uses less storage. When dense representation is optimal, it maintains the current layout order.
Returns a matrix in dense or sparse column major format, whichever uses less storage.
Returns a matrix in dense or sparse column major format, whichever uses less storage.
Returns a matrix in dense or sparse row major format, whichever uses less storage.
Returns a matrix in dense or sparse row major format, whichever uses less storage.
Get a deep copy of the matrix.
Get a deep copy of the matrix.
Applies a function f to all the active elements of dense and sparse matrix.
Applies a function f to all the active elements of dense and sparse matrix. The ordering
of the elements are not defined.
the function takes three parameters where the first two parameters are the row
and column indices respectively with the type Int, and the final parameter is the
corresponding value in the matrix with type Double.
whether the matrix is transposed.
whether the matrix is transposed. If true, values stores the matrix in
row major.
