All Implemented Interfaces:

java.io.Serializable, DMatrix, DMatrixFixed, Matrix

public class DMatrix3x3
extends java.lang.Object
implements DMatrixFixed

Fixed sized 3 by DMatrix3x3 matrix. The matrix is stored as class variables for very fast read/write. aXY is the value of row = X and column = Y.

                double a12,
                double a13,
                double a21,

get

public double get(int row,
                  int col)

Description copied from interface: DMatrix

Returns the value of value of the specified matrix element.

Specified by:

get in interface DMatrix

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

Returns:

The specified element's value.

unsafe_get

public double unsafe_get(int row,
                         int col)

Description copied from interface: DMatrix

Same as DMatrix.get(int, int) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.

Specified by:

unsafe_get in interface DMatrix

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

Returns:

The specified element's value.

set

public void set(int row,
                int col,
                double val)

Description copied from interface: DMatrix

Sets the value of the specified matrix element.

Specified by:

set in interface DMatrix

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

val - The element's new value.

unsafe_set

public void unsafe_set(int row,
                       int col,
                       double val)

Description copied from interface: DMatrix

Same as DMatrix.set(int, int, double) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.

Specified by:

unsafe_set in interface DMatrix

Parameters:

row - Matrix element's row index..

col - Matrix element's column index.

val - The element's new value.

set

public void set(Matrix original)

Description copied from interface: Matrix

Sets this matrix to be identical to the 'original' matrix passed in.

Specified by:

Returns:

Number of elements in this matrix.

copy

public <T extends Matrix> T copy()

Description copied from interface: Matrix
