| Research Abstract |
This research developed a library for multiple-precision arithmetic which enables us to change the precision of computation without modifying the existing codes and a library for verified numerical computation which makes it possible to use interval arithmetic very easily in the user programs. And a method for numerical computation with guaranteed arbitrary accuracy was proposed which controls adaptively the bit-length of the mantissa in multiple-precision arithmetic. A library for high quality numerical computation was developed based on the libraries above and the proposed method. We have developed a tool for modeling and simulation of control systems which provides the easy-to-use user interface and enables us to utilize high quality numerical computation.
