Abstract

In this paper, we discuss generating a *-algebra over the real field with a set of symmetric matrices. This is motivated by an application in structural engineering. We show that any *-algebra can be generated with at most four randomly-chosen symmetric matrices. The proof relies on the structure theorem for *-algebras and the notion of genericity in eigenvalue structure.
