Solving linear systems: LU factorization - Duke University

A matrix equation in the form $${\displaystyle L\mathbf {x} =\mathbf {b} }$$ or $${\displaystyle U\mathbf {x} =\mathbf {b} }$$ is very easy to solve by an iterative process called forward substitution for lower triangular matrices and analogously back substitution for upper triangular matrices. The process is so called … See more In mathematics, a triangular matrix is a special kind of square matrix. A square matrix is called lower triangular if all the entries above the main diagonal are zero. Similarly, a square matrix is called upper triangular if all the … See more A matrix of the form is called a lower triangular matrix or left triangular matrix, and analogously a matrix of the form See more Unitriangular matrix If the entries on the main diagonal of a (upper or lower) triangular matrix are all 1, the matrix is called … See more Upper triangularity is preserved by many operations: • The sum of two upper triangular matrices is upper triangular. • The product of two upper triangular … See more The transpose of an upper triangular matrix is a lower triangular matrix and vice versa.
