block tridiagonal
 
Can anyone tell me or send me a code "fortran" for solving a block-tridiagonal matrix?

Efficient Block tridiagonal matrix solver
 
Can anyone tell me which algorithm is more efficient and precise for solving the block-tridiagonal matrix? The LU decompostion algorithm or the Thoma algorithm (for the Thomas algorithm we need to calculate a matrix inverse )
