1910	 An Algorithm for Solving a Special Class of Tridiagonal Systems of Linear Equations	 An algorithm is presented for solving a system of linear equation Bu k where B is tridiagonal and of a special form. It is shown that this algorithm is almost twice as fast as the Gaussian elimination method usually suggested for solving such systems. In addition explicit formulas for the inverse and determinant of the matrix B are given. tridiagonal Gaussian elimination central difference
