Abstract
We present a new class of matrix models which are manifestly symmetric under the -duality transformation of the target space. The models may serve as a nonperturbative regularization for the -duality symmetry in continuum string theory. In particular, it now becomes possible to extract winding modes explicitly in terms of extended matrix variables.
