Advanced Computational Techniques

ABOUT THE COURSE: There are several basic online courses on numerical methods available, however a course which can provide a foundation for the advanced numerical modeling and scientific computing is infrequent. This course is designed as an introductory course on advanced topics on numerical methods for engineering and science students. It is intended to teach the implementation of numerical methods rather than just provide theoretical foundations of the methods. Scientific computing is an integral part of several disciplines including computational mathematics. The completion of this course will equipped the students in handling advanced computational tools. All the methods will be illustrated by working out several examples. Pre-requisite for this course is the basic knowledge of undergraduate calculus and elementary numerical methods.INTENDED AUDIENCE: UG or PG of any Engineering course, Mathematics,Physics and Postgraduate student of Mathematics/Mechanical/Aerospace/Chemical EngineeringPREREQUISITES: Basic UG course in Mathematics/ Undergraduate Calculus
