Linear System Analyzer Computational Components

The "meat" of the LSA is its linear system codes, which comprise its "components". This should be distinguished from the LSA subsystems, the reusable software infrastructure parts that can be applied to form PSEs in other problem domains.

The general categories in which the linear system components have been grouped are

Components currently available are listed below. Please note that the hyperlinks below are to the original library source of the codes, which in most cases have been modified to constitute stand-alone components.

These are not an exhaustive compendium of numerical software available for large sparse linear systems, but they span enough of the common operations to demonstrate the application of the LSA.
