    An approach is presented to solve bordered tridiagonal linear equations (BTLES). By the approach, a BTLE is first converted into three or more tridiagonal linear equations (TLES) that are independent each other, then the solution of the BTLE can be obtained via the solutions of the TLES. Since the TLES are independent each other, their solution can be obtained via parallel computing under heteroge... View full abstract»
