Jordan canonical form — an 'almost' diagonalised matrix, where the only non-zero elements appear on the lead and super-diagonals. Linear independence — two or more vectors are linearly independent if there is no way to construct one from linear combinations of the others. Matrix exponential — defined by the exponential series. Matrix representation of conic sections Pseudoinverse — a generalization of the inverse matrix. Quaternionic matrix - matrix using quaternions as numbers Row echelon form — a matrix in this form is the result of applying the forward elimination procedure to a matrix (as used in Gaussian elimination). Wronskian — the determinant of a matrix of functions and their derivatives such that row n is the (n-1)th derivative of row one. |
