Let
$n\geq 2$ be an integer. In [5] and [6], an
$n\times n$ $\mathbb A$-full matrix algebra over a field
$K$ is defined to be the set
$\mathbb M_n(K)$ of all square
$n\times n$ matrices with coefficients in
$K$ equipped with a multiplication defined by a structure system
$\mathbb A$, that is, an
$n$-tuple of
$n\times n$ matrices with certain properties. In [5] and [6], mainly
$\mathbb A$-full matrix algebras having (0,1)-structure systems are studied, that is, the structure systems
$\mathbb A$ such that all entries are 0 or 1. In the present paper we study
$\mathbb A$-full matrix algebras having non (0,1)-structure systems. In particular, we study the Frobenius
$\mathbb A$-full matrix algebras. Several infinite families of such algebras with nice properties are constructed in Section 4.
