Linjära ekvationssystem

determinant of A is zero, there can be infinite solutions. One of the infinitely … Calling lu for numeric arguments that are not symbolic objects invokes the MATLAB ® lu function. The thresh option supported by the MATLAB lu function does not affect symbolic inputs. If you use 'matrix' instead of 'vector', then lu returns permutation matrices, as it does by default. L and U are nonsingular if and only if A is nonsingular. /// Decomposes a square matrix A by PA=LU and returns L, U and P. Tuple!

This is a good thing to always try to do. But sometimes if the difference between the pivots is small, a user might not want this feature. In Matlab, let's find the LU decomposition of the matrix A = [-2 1 -3; 6 -1 8; 8 3 -7] Write this instruction in the command window or within a script: [L, U] = lu(A) And the Matlab answer is: https://se.mathworks.com/matlabcentral/answers/67757-gaussian-elimination-or-lu#answer_79200.
