Method Detail

assign

public void assign(int val)

Description copied from interface: IntDenseMatrix

Assign the same given score to all cells of the matrix

Specified by:

assign in interface IntDenseMatrix

Parameters:

val - the score

add

public boolean add(int row,
                   int column,
                   int score)

Specified by:

add in interface IntDenseMatrix

setInt

public boolean setInt(int row,
                      int column,
                      int score)

Specified by:

setInt in interface IntDenseMatrix

getRowSum

public long getRowSum(int row)

Specified by:

getRowSum in interface IntDenseMatrix

Parameters:

row - the index of the row

Returns:

the summation score of the given row.

getColumnSum

public long getColumnSum(int column)

Specified by:

getColumnSum in interface IntDenseMatrix

Parameters:

column - the index of the column

Returns:

the summation score of the given column

getInt

public int getInt(int row,
                  int column)

Description copied from interface: Matrix

Return the score stored in the specified cell. If the score is double-typed, it will be coverted to an integer.

Specified by:

getInt in interface Matrix

Parameters:

row - the row index of the cell

column - the column index of the cell

Returns:

the score stored in the cell

getDouble

public double getDouble(int row,
                        int column)

Description copied from interface: Matrix

Return the score stored in the specified cell. If the score is integer-typed, it will be coverted to a double.

Specified by:

getDouble in interface Matrix

Parameters:

row - the row index of the cell

column - the column index of the cell

Returns:

the score stored in the cell

saveTo

public void saveTo(String filename,
                   boolean binary)

saveTo

public void saveTo(String filename)

print

public void print(PrintWriter out)

close

public void close()

Description copied from interface: Matrix

Close the matrix and release all resources.

Specified by:

close in interface Matrix
