Method Detail

identity

public static MatrixI2x2F identity()

Returns:

The identity matrix

newFromColumns

                                         VectorReadable2FType 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 MatrixI2x2F newFromReadable(MatrixReadable2x2FType m)

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

Parameters:

equals

public boolean equals(@Nullable
                      Object obj)

Overrides:

equals in class Object

getRow2F

public <V extends VectorWritable2FType> void getRow2F(int row,
                                                      V out)

Description copied from interface: MatrixReadable2x2FType

Retrieve row row, saving the result to out.

Specified by:

getRow2F in interface MatrixReadable2x2FType

Type Parameters:

V - The precise type of writable vector.

Parameters:

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

out - The output vector.

getRow2FUnsafe

public <V extends VectorWritable2FType> void getRow2FUnsafe(int row,
                                                            V out)

Description copied from interface: MatrixReadable2x2FType

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:

getRow2FUnsafe in interface MatrixReadable2x2FType

Type Parameters:

V - The precise type of writable vector.

Parameters:

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

out - The output vector.

The value at row 0, column 1

getR1C1F

public float getR1C1F()

Specified by:

getR1C1F in interface MatrixReadable2x2FType

Returns:

The value at row 1, column 1

getRowColumnF
