The CDA Method of Polynomial Multiple Root Determination.

The links below are to the Sections of the paper on the Cascade Differential Analysis, (CDA), method, for the precise determination of the multiple plus singular roots of high order polynomials, when those roots occur in any combination. The method is implemented here via a series of three EXCEL spreadsheets in Bairstow3.zip.

Introduction - The first section contains a title page, a brief abstract, the main introduction and the first part of the description containing implementation coverage in detail.

Computation Time et al - The second section provides details on implementation computation time, accuracy and other main features providing a degree of operational flexibility.

Conclusions et al - The final Section provides brief conclusions, and an Appendix providing guidelines on performing efficient root iteration using the Polynomial Construction Spreadsheet that is also included in updated form in this implementation. References are also included here.
