Functions  
subroutine  clagtm (trans, n, nrhs, alpha, dl, d, du, x, ldx, beta, b, ldb) 
CLAGTM performs a matrixmatrix product of the form C = αAB+βC, where A is a tridiagonal matrix, B and C are rectangular matrices, and α and β are scalars, which may be 0, 1, or 1.  
subroutine  dlagtm (trans, n, nrhs, alpha, dl, d, du, x, ldx, beta, b, ldb) 
DLAGTM performs a matrixmatrix product of the form C = αAB+βC, where A is a tridiagonal matrix, B and C are rectangular matrices, and α and β are scalars, which may be 0, 1, or 1.  
subroutine  slagtm (trans, n, nrhs, alpha, dl, d, du, x, ldx, beta, b, ldb) 
SLAGTM performs a matrixmatrix product of the form C = αAB+βC, where A is a tridiagonal matrix, B and C are rectangular matrices, and α and β are scalars, which may be 0, 1, or 1.  
subroutine  zlagtm (trans, n, nrhs, alpha, dl, d, du, x, ldx, beta, b, ldb) 
ZLAGTM performs a matrixmatrix product of the form C = αAB+βC, where A is a tridiagonal matrix, B and C are rectangular matrices, and α and β are scalars, which may be 0, 1, or 1.
