Jacques Hadamard designed a type of these structures used to create error-correcting code. Some of these are classified as upper or lower triangular, and these are skew-symmetric if their opposite equals their transpose. These structures are used to represent graphs using degrees or adjacency. Putting an augmented one of these into reduced row echelon [eh-cheh-lon] form can be used to solve a system of equations. Name these rectangular arrangements of numbers, the square examples of which have determinants.
