To solve the equations

Ax = b,

where A is the Hermitian positive definite tridiagonal matrix

A = $\displaystyle \left(\vphantom{ \begin{array}{ccccc} 16.0 & 16.0 - 16.0 i & 0 ... ...0 i & 46.0 & 1.0 + 4.0 i \\ 0 & 0 & 1.0 - 4.0 i & 21.0 \end{array} }\right.$ $\displaystyle \begin{array}{ccccc} 16.0 & 16.0 - 16.0 i & 0 & 0 \\ 16.0 + 1... ...18.0 - 9.0 i & 46.0 & 1.0 + 4.0 i \\ 0 & 0 & 1.0 - 4.0 i & 21.0 \end{array}$ $\displaystyle \left.\vphantom{ \begin{array}{ccccc} 16.0 & 16.0 - 16.0 i & 0 ... ...0 i & 46.0 & 1.0 + 4.0 i \\ 0 & 0 & 1.0 - 4.0 i & 21.0 \end{array} }\right)$

and

b = $\displaystyle \left(\vphantom{ \begin{array}{r} 64.0 + 16.0 i \\ 93.0 + 62.0 i \\ 78.0 - 80.0 i \\ 14.0 - 27.0 i \end{array} }\right.$ $\displaystyle \begin{array}{r} 64.0 + 16.0 i \\ 93.0 + 62.0 i \\ 78.0 - 80.0 i \\ 14.0 - 27.0 i \end{array}$ $\displaystyle \left.\vphantom{ \begin{array}{r} 64.0 + 16.0 i \\ 93.0 + 62.0 i \\ 78.0 - 80.0 i \\ 14.0 - 27.0 i \end{array} }\right)$ .

Details of the LDL^H factorization of A are also output.
