Compute the LU factorization of a matrix and examine the resulting factors. LU factorization is a way of decomposing a matrix A into an upper triangular matrix U, a lower triangular matrix L, and a permutation matrix P such that PA = LU. The LU Solver block solves the linear system AX = B by applying LU factorization to the M -by- M matrix at the A port. The input to the B port is the right side M -by- N matrix, B. The M -by- N matrix output X is the unique solution of the equations.
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 Solving system of equations using Lu Method and Learn more about lu, matrix, warning, error, system of equations MATLAB does not use any symbolic LU prefactorization to determine the memory requirements and set up the data structures in advance.
Appears as LU and x=A\b in MATLAB. • CHOLMOD: supernodal Cholesky. Appears as CHOL and x=A\b in MATLAB. Now with CUDA acceleration, in collaboration with NVIDIA. • SPQR: multifrontal QR. Appears as QR and x=A\b in MATLAB, with CUDA acceleration. • KLU and BTF: sparse LU factorization, well-suited for circuit simulation.
Hereby a matrix will be decomposed into an upper trangular and an lower triangular matrix. Description.

Solving this linear equation system should be according to the following steps - 1. define y - s.t Ux=y 2. 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 ?
