In Reply to: Solution of Block Toeplitz linear equations. posted by Lachlan Hill on August 08, 1997 at 08:36:18:

: Hello,

: I was wondering if anyone could help me find a routine that will solve

: a system of linear equations. The system takes the form of Tx = y

: where x and y are column vectors. T is a symmetric Hermitian Block Toeplitz

: matrix of the form

: | A B |

: | Bt C |

: where A and C themselves are symmetric Toeplitz matrices and B is a non-

: symmetric toeplitz matrix. In the toeplitz library on netlib, I can only

: find routines for solving systems where matrices on the diagonals are the

: same.

: Any help would be greatly appreciated

Lachlan,

According to one of our gurus, you might want to look in

the toeplitz directory of Netlib. He didn't think

there were codes to solve your problem specifically,

but that the routines there can be used to solve each

step of the 2x2 system you have.

Hope this helps!
