Web Upper Triangular Form Consider two n n complex matrices A and B We say that A and B are similar and write A B if there is an invertible matrix C such that A C 1BC An n 1 matrix C is called unitary if C C or equivalently if Upper Triangular Form Stanford University. Web 10 years ago It does not matter and the sign will be the same the transpose of a lower triangular matrix is an upper triangular matrix and vice versa and the determinant of the transpose of a matrix is the same as the determinant of that matrix Web The main reason why they ask you to transform it into an upper triangular matrix is that the determinant is just the multiplication of all the elements on the first diagonal There are some algorithms to transform a matrix for example the LU decompostion such that A LU where L is an lower triangular matrix and U an upper triangular one
