The characteristic equation is used to find important values for them for multiplication by vectors.
These entities can be factored using singular value decomposition. The characteristic equation is used to find important values for them for multiplication by vectors. The Jacobian type is used for change of variables in multivariate calculus, and diagonal ones have their eigenvalues along the main diagonal. These entities can be used in conjunction with Cramer's rule or row elimination in order to solve systems of linear equations. For the two-by-two type, their determinant is ad - bc, and multiplication of these entities is non-commutative. For 10 points, name these rectangular arrays of numbers.
