Matrix Computation and its applications

via Swayam

Overview

This course deals with applications of matrices to a wide range of areas of engineering and science. Initial some basics of linear algebra is discussed followed by matrix norms and sensitivity and condition number of the matrices. In this course , we will also discuss psudo-inverse of a matrix of any dimension (m x n) using Moore- Penrose theorem. Singular value decomposition of a general matrix is also discussed along with applications. Householder transformations, QR factorization will also be covered.INTENDED AUDIENCE :UG/PGPRE-REQUISITES : Some knowledge of matrix theoryINDUSTRY SUPPORT : Any software/financial industry will be interested.
