Matrix extraction API

Required Methods

fn row(&self, r: isize) -> Matrix<T>

Returns the r'th row vector

fn col(&self, c: isize) -> Matrix<T>

Returns the c'th column vector

fn sub_matrix(&self, start_row: isize, start_col: isize, num_rows: usize, num_cols: usize) -> Matrix<T>

Extract a submatrix from the matrix rows can easily repeat if the number of requested rows is higher than actual rows cols can easily repeat if the number of requested cols is higher than actual cols

fn ut_matrix(&self) -> Matrix<T>

Returns the upper triangular part of the matrix

fn lt_matrix(&self) -> Matrix<T>

Returns the lower triangular part of the matrix
