This book acquaints the readers with the mathematical and computer oriented models extensively used in a variety of disciplines of social and engineering sciences. The mathematical models find tremendous applications through their use in facilitating economic evaluation and in a number of decision-making contexts including risk assessment, service planning and capacity modeling. In the present era, the applications of computational techniques to the disciplines of linear algebra, probability and statistics are of great importance. These three areas of continuous mathematics are critical in many parts of computer science, including machine learning, scientific computing, computer vision, computational biology, computational finance, natural language processing, and computer graphics.
