In this section we introduce the concept of an \textit{elementary matrix}. Elementary matrices are relatively simple objects, as their name suggests, but as we will see, they give us a simple method ...

ONE of the serious limitations to scientific development is the amount of labour involved in computation, and the authors of this book on matrices have put on record processes which they have found of ...

the inverse of an elementary matrix. The following theorem ensures that the inverse of each elementary matrix is itself an elementary \item If $E$ is obtained by ...

Abstract: An iterative method of constructing projection matrices on the intersection of subspaces is considered, using a product of elementary matrices. A convergence theorem with two natural ...

An elementary matrix is one obtained by doing a single row operation to an identity matrix. Doing a row operation r to a matrix has the same effect as multiplying that matrix on the left by the ...

Abstract: Measurement of elementary matrix provides complete component characterization All important dispersion properties are readily available from matrix N; this eliminates the need for complex ...
