Method Detail

identity

public static MatrixI2x2D identity()

Returns:

                                         VectorReadable2DType column_1)

Construct a new immutable 2x2 matrix from the given columns.

Parameters:

column_0 - The first column

column_1 - The second column

Returns:

A new 2x2 matrix

newFromReadable

public static MatrixI2x2D newFromReadable(MatrixReadable2x2DType m)

equals

public boolean equals(@Nullable
                      Object obj)

Overrides:

equals in class Object

getRow2D

public <V extends VectorWritable2DType> void getRow2D(int row,
                                                      V out)

Description copied from interface: MatrixReadable2x2DType

Retrieve row row, saving the result to out.

Specified by:

getRow2D in interface MatrixReadable2x2DType

Type Parameters:

V - The precise type of writable vector.

Parameters:

row - The index of the row, starting at 0.

out - The output vector.

getRow2DUnsafe

public <V extends VectorWritable2DType> void getRow2DUnsafe(int row,
                                                            V out)

Description copied from interface: MatrixReadable2x2DType

Retrieve row row, saving the result to out. No bounds checking is performed for row, and out-of-bounds values result in undefined behaviour.

Specified by:

getRow2DUnsafe in interface MatrixReadable2x2DType

Type Parameters:

V - The precise type of writable vector.

Parameters:

row - The index of the row, starting at 0.

out - The output vector.

getR1C1D

public double getR1C1D()

Specified by:

getR1C1D in interface MatrixReadable2x2DType

Returns:

The value at row 1, column 1
