“…It is well known that the Stein matrix equation
is widely used in the fields of optimal or robust stabilization of stochastic linear control systems, filtering theory for discreteâtime largeâscale dynamical systems, and the stability analysis of linear time invariant systems, see, for example, Reference
1â7. Recently, many scholars have found that many problems in control theory, partial differential equations, mechanics, and many other problems can be attributed to solving various tensor equations
8â16 . Therefore, iterative methods in their tensor forms have become one of the hot topics in numerical algebra.…”
