Elementary Row Operations and Their Inverse
... In the previous section, we mentioned that invertible matrices will play an important in our study of linear algebra; thus it will be helpful to be able to 1. determine whether or not a specific matrix has an inverse, and 2. find inverses when they exist. The following theorem will provide us with sev ...

A Superfast Algorithm for Confluent Rational Tangential
... Abstract. Various problems in pure and applied mathematics and engineering can be reformulated as linear algebra problems involving dense structured matrices. The structure of these dense matrices is understood in the sense that their n2 entries can be completeley described by a smaller number O(n) ...
