Few calculator users are aware of the computational power beneath their fingers. Algorithms designed for one of the many hand-held calculators that use RPN (Reverse Polish Notation) can solve remarkably complex numerical problems, ordinarily given to large computers.

This book explains how to write concise and elegant algorithms for meeting specific, individual needs and for solving numerical problems of surprising complexity. Using only a RPN calculator and the methods supplied, scientists, engineers, and students can numerically integrate differential equations, fit curves to data using least-squares techniques, solve transcendental algebraic functions (such as Bessel functions). In addition, existing algorithms can be simplified and streamlined.

Algorithms for RPN Calculators progresses logically: you will understand and benefit from the first chapters even if your background includes only high-school mathematics; later chapters deal with more complex problems involving calculus. And, a large section of the book gives actual RPN algorithms for a variety of common problems. These are written to be readily adapted or directly used on any RPN calculator. This section alone constitutes a valuable practical reference.

Each chapter ends with exercises (problem sets), and an appendix contains numerical answers. In addition, the book includes a critique of present calculator designs with suggestions for future developments.

Über diesen Autor

John A. Ball is a radio astronomer at the Center for Astrophysics (Harvard College Observatory and Smithsonian Astrophysical Observatory) in Cambridge, Massachusetts.

Dr. Ball was born in Ravenna, Nebraska in 1935 and educated at the University of Nebraska (B.S. in electrical engineering) and at Harvard (Ph.D. in astronomy). He is an expert in the techniques of data acquisition and data reduction in spectral-line radio astronomy. He has been involved in radio-astronomical observing programs at many of the major radio observatories. He participated in the discovery of the following new molecules in interstellar space: methyl alcohol, formic acid, acetaldehyde, SO, ethyl alcohol, and NS. Dr. Ball is a member of Sigma XI, Pi Mu Epsilon, Eta Kappa Nu, The Institute of Electrical and Electronics Engineers, the American Astronomical Society, the International Astronomical Union, the International Scientific Radio Union, the American Association for the Advancement of Science, the Audio Engineering Society, and the American Association of Physics Teachers.

In his spare time, Dr. Ball writes about extraterrestrial intelligence, electronic music, and RPN calculators.
