public MutableAbstractMatrix()

Method Detail

allocate

protected abstract void allocate(MatrixBackingBuffer buffer)

Calls MatrixBackingBuffer.allocate(int) on the used buffer.

Parameters:

buffer - buffer

fill

public void fill(float value)

Description copied from interface: MutableMatrix

Fills all writable elements of this matrix with the given value.

Specified by:

fill in interface MutableMatrix

Parameters:

value - value

copy

public void copy(float[] values)

Description copied from interface: MutableMatrix

Copies values from the provided array row by row to this matrix.

Specified by:

copy in interface MutableMatrix

Parameters:

values - values

copy

public void copy(Matrix fromMatrix)

Description copied from interface: MutableMatrix

Copies values from another Matrix to this matrix. If this matrix does not support the setting of certain elements (e.g. SymmetricBandMatrix), the method fails silently, i.e. no values are copied, and no exception is raised.

Specified by:

copy in interface MutableMatrix

Parameters:

fromMatrix - other matrix

copy

public void copy(Matrix fromMatrix,
                 int fromRow,
                 int fromColumn,
                 int toRow,
                 int toColumn,
                 int rows,
                 int columns)

Description copied from interface: MutableMatrix

Copies values from a defined offset from another matrix to a defined offset of this matrix. If this matrix does not support the setting of certain elements (e.g. SymmetricBandMatrix), the method fails silently, i.e. no values are copied, and no exception is raised.

Specified by:

copy in interface MutableMatrix

Parameters:

fromMatrix - other matrix

fromRow - row start offset of from matrix

fromColumn - column start offset of from matrix

toRow - column start offset of this matrix

toColumn - column start offset of this matrix

rows - number of rows to copy

columns - number of column to copy

copy

public static void copy(Matrix fromMatrix,
                        int fromRow,
                        int fromColumn,
                        MutableMatrix toMatrix,
                        int toRow,
                        int toColumn,
                        int rows,
                        int columns)

set

public void set(int row,
                int column,
                float value)

Description copied from interface: MutableMatrix

Sets the given value.

Specified by:

set in interface MutableMatrix

Parameters:

row - row

column - column

value - value

setColumn

public void setColumn(int column,
                      float[] values)

Description copied from interface: MutableMatrix

Sets the given values.

Specified by:

setColumn in interface MutableMatrix

Parameters:

column - column

values - values

setRow

public void setRow(int row,
                   float[] values)

Description copied from interface: MutableMatrix

Sets the given values.

Specified by:

setRow in interface MutableMatrix

Parameters:

row - row

values - values

set

protected void set(int index,
                   float value)
