Solving systems of linear equations on analog computers

Solving systems of linear equations is a central task not only in artificial intelligence. This article outlines a technique making it possible to employ analog computers to the solution of such equations. Using iterative techniques it is even possible to setup a hybrid computer, i. e. a combination of a classic digital and an analog computer, where the analog portion can be used as a co-processor. If the solutions obtained by pure analog computing are not of the required accuracy, it is possible to use these as initial vectors for a classic iterative algorithm running on the digital computer to further enhance the precision of the solution obtained.
