This is the first session on my course Matrix methods . Here , you will learn various methods to convert a matrix to its echelon form and normal form. Given a matrix A, you will learn how to find non singular matrices P and Q such that PAQ is normal. A useful topic in college maths. The full course includes Guass Elimination method, Gauss Jordan method, Gauss Seidel method and finding the inverse of a matrix using adjoint. You can contact me for further details.
