Elementary Matrix
In mathematics, an elementary matrix is nothing but a matrix obtained by performing only one elementary transformation. They can be denoted as follows:
- Elementary matrix obtained by interchanging i, jth rows of I is denoted by Eij.
- Elementary matrix obtained by multiplying ith row of I with non-zero constant K is denoted by Ei (k)
- Elementary matrix obtained by adding products of elements of jth row of I and a constant m is added to the corresponding elements of ith row, is denoted by Eij(m).
