Tridiagonal Solver for Ax=b

I have been using dgesv for solving Ax=b, but my matrix A happens to be tridiagonal. I am wondering if there are any specific solvers in MKL that handle Ax=b where A is tridiagonal. Thanks in advance!

Matt, 

These two LAPACK function support the  tridiagonal matrix. Can yo check if it works for you?
