Thomas algorithm for tridiagonal matrix

In numerical linear algebra, the tridiagonal matrix algorithm, also known as the Thomas algorithm (named after Llewellyn Thomas), is a simplified form of Gaussian elimination that can be used to solve tridiagonal systems of equations. A tridiagonal system for n unknowns may be written as See more The derivation of the tridiagonal matrix algorithm is a special case of Gaussian elimination. Suppose that the unknowns are $${\displaystyle x_{1},\ldots ,x_{n}}$$, and that the equations to … See more In some situations, particularly those involving periodic boundary conditions, a slightly perturbed form of the tridiagonal system may need to … See more WebThe implicit method counters this with the ability to substantially increase the timestep. The method used to solve the matrix system is due to Llewellyn Thomas and is known as the …
