Query: Toeplitz Matrices acting on the $\ell^2$-space of an imprimitivity
  bimodule   We give a definition of Toeplitz matrix acting on the $\ell^2$-space of an
imprimitivity bimodule $X$ over a $C^*$-algebra $A$. We characterize the set of
Toeplitz matrices as the closure in a certain topology of the image of the left
regular representation of the crossed product $A\rtimes X$.
