Matrix Operations
... elements (numbers in the matrix) are indexed by their position down, then across. So, A12 = 2. A23 = 6. Vectors are either rows or columns of a matrix. They are represented by letters that are either underlined, or have a squiggly under them. So, an example of a row vector of matrix A is A =[1 2 3]. ...

Finding the Inverse of a Matrix
... The Inverse of a 2 2 Matrix Using Gauss-Jordan elimination to find the inverse of a matrix works well (even as a computer technique) for matrices of 3 3 dimension or greater. For 2 2 matrices, however, many people prefer to use a formula for the inverse (see next slide) rather than GaussJorda ...
