Solve is only for symbolic calculations in matlab. If the functions inside the matrix are trigonometric, and 12x12 matrix, Man then for sure you end up with too complex function that is most LU-decomposition is basically a modified form of Gaussian elimination. LU decomposition is an effective procedure for solving LP problems, this method can help in accelerating the computation. Over and above, the development of computers and software packages has made LU decomposition easy and attractive method to solve large-scale LP MATLAB features a family of add-on application-specific solutions called toolboxes.

Lu solver matlab

Introduced in R2012b The output of solve can contain parameters from the input equations in addition to parameters introduced by solve. Parameters introduced by solve do not appear in the MATLAB workspace. They must be accessed using the output argument that contains them. Alternatively, to use the parameters in the MATLAB workspace use syms to This is MATLAB implementation for LU decomposition, forward substitution, backward substitution, and linear system solver.

linsolve warns if A is ill conditioned (for square matrices) or rank deficient (for rectangular matrices).

% LU factorization of a tridiagonal n by n matrix A % Diagonal part of A is b(1), , b(n) % Vector above muted triangular, it will dispense with L-U factorization and solve the linear equation directly using forward or backward substitution. Matlab also uses. Compare your function with Matlab lu function.
