Method Detail

indexOfLargestInColumn

default long indexOfLargestInColumn(long col)

indexOfLargestInColumn

long indexOfLargestInColumn(long row,
                            long col)

Parameters:

row - First row to investigate

col - The column

Returns:

The row-index of the largest absolute value in a column, starting at the specified row.

indexOfLargestInRow

default long indexOfLargestInRow(long row)

indexOfLargestInRow

long indexOfLargestInRow(long row,
                         long col)

Parameters:

row - The row

col - The first column to investigate

Returns:

The column-index of the largest absolute value in a row, starting at the specified column.

indexOfLargestOnDiagonal

default long indexOfLargestOnDiagonal()

indexOfLargestOnDiagonal

long indexOfLargestOnDiagonal(long first)

Parameters:

first - The first row/column to investigate

Returns:

The row/column-index of the largest absolute value on the main diagonal, starting at the specified row/column.
