Hi!
I was wondering whether there is a LAPACK/BLAS routine for matrix-vector product where the matrix is a symmetric tridiagonal matrix? I was able to find an auxiliary LAPACK routine (xLAGTM) for a general tridiagonal matrix, but I would also like one for symmetric tridiagonal matrices. It's strange if there is no matrix-vector product for symmetric tridiagonal matrices, when the matrix-format is generally supported?
Thanks!
