Constructor Detail

ViewMatrix

public ViewMatrix()

Constructor for Externalizable interface.

ViewMatrix

public ViewMatrix(Matrix parent,
                  int rowOff,
                  int colOff,
                  int rows,
                  int cols)

Parameters:

parent - Backing parent Matrix.

rowOff - Row offset to parent matrix.

colOff - Column offset to parent matrix.

rows - Amount of rows in the view.

cols - Amount of columns in the view.

ViewMatrix

public ViewMatrix(MatrixStorage sto,
                  int rowOff,
                  int colOff,
                  int rows,
                  int cols)

Parameters:

sto - Backing parent MatrixStorage.

rowOff - Row offset to parent storage.

colOff - Column offset to parent storage.

rows - Amount of rows in the view.

cols - Amount of columns in the view.

Method Detail

copy

public Matrix copy()

Clones this matrix.

NOTE: new matrix will have the same flavor as the this matrix but a different ID.

Specified by:

copy in interface Matrix

Overrides:

copy in class AbstractMatrix

Returns:

New matrix of the same underlying class, the same size and the same values.

like

public Matrix like(int rows,
                   int cols)

Creates new empty matrix of the same underlying class but of different size.

NOTE: new matrix will have the same flavor as the this matrix but a different ID.

Parameters:

rows - Number of rows for new matrix.

cols - Number of columns for new matrix.

Returns:

New matrix of the same underlying class and size.

likeVector

public Vector likeVector(int crd)

Creates new empty vector of compatible properties (similar or the same flavor) to this matrix.

Parameters:

crd - Cardinality of the vector.

Returns:

Newly created empty vector "compatible" to this matrix.
