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.
