Download or read book Study of Natural Class of Intervals Using (-∞, ∞) and (∞, -∞) written by W. B. Vasantha Kandasamy, Florentin Smarandache, D. Datta, H. S. Kushwaha, P. A. Jadhav and published by Infinite Study. This book was released on 2011 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the authors introduce and study the properties of natural class of intervals built using (-, ) and (, -). The operations on these matrices with entries from natural class of intervals behave like usual reals. So working with these interval matrices takes the same time as usual matrices. Hence, when applying them to fuzzy finite element methods or finite element methods the determination of solution is simple and time saving.
