Strict triangular form 中文
WebMar 24, 2024 · Strictly Lower Triangular Matrix. A lower triangular matrix having 0s along the diagonal as well as the upper portion, i.e., a matrix such that for . Written explicitly, Lower Triangular Matrix, Strictly Upper Triangular Matrix , Triangular Matrix. WebThe 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.
