The determinant of a triangular matrix, either upper or lower, and of any size, is just the product of its diagonal entries. This single property immensely simplifies the ordinarily laborious calculation of determinants. Here are some examples for 2x2 and 3x3 matrices. Lower Triangular 2x2 Matrix has a determinant of ad-c0 = ad. the matrix Awe mean a decomposition of the form A= UV T, where U and V are orthogonal matrices (representing rotations) and is a diagonal matrix (representing a stretch). Introduction Matrix analysis is ubiquitous in mathematics and its applications. Due to the context of this encyclopedia, we restrict our discussion to real matrices only.
