This method factors a matrix as a product of lower triangular and upper triangular matrices. LU method can be viewed as matrix form of Gaussian elimination to solve system of linear equation. X = linsolve (A,B) solves the linear system AX = B using one of these methods: When A is square, linsolve uses LU factorization with partial pivoting. For all other cases, linsolve uses QR factorization with column pivoting. linsolve warns if A is ill conditioned (for square matrices) or rank deficient (for rectangular matrices). I need to write a program to solve matrix equations Ax=b where A is an nxn matrix, and b is a vector with n entries using LU decomposition.

This video explains how to use LU Decomposition to solve a system of linear equations.Site: http://mathispower4u.comBlog: http://mathispower4u.wordpress.com X = linsolve(A,B,opts) uses an appropriate solver as determined by the options structure opts. The fields in opts are logical values describing properties of the matrix A. For example, if A is an upper triangular matrix, you can set opts.UT = true to make linsolve use a solver designed for upper triangular matrices. Solve Ax=b with LU factorization.

solve Ly=b by forward substitution 3. solve Ux=y by backward substitution 4. return y Edit 2 : I found linalg::matlinsolveLU but I didn't try it cause I have too old version (R2010a) . Is it working for anyone ? LU Factorization method, also known as LU decomposition method, is a popular matrix decomposing method of numerical analysis and engineering science.

matlab documentation: LU decomposition. Example. Hereby a matrix will be decomposed into an upper trangular and an lower triangular matrix. Description. The LU Inverse block computes the inverse of the square input matrix A by factoring and inverting row-pivoted variant Ap. L is a lower triangular square matrix with unity diagonal elements, and U is an upper triangular square matrix. The block outputs the inverse matrix A-1. In numerical analysis and linear algebra, lower–upper (LU) decomposition or factorization factors a matrix as the product of a lower triangular matrix and an upper triangular matrix.
