Abstract
Previously matrix model actions for "fuzzy" fields have been proposed using noncommutative geometry. They retained "topological" properties extremely well, being capable of describing instantons, theta -states, the chiral ano maly, and even chiral fermions with no "doubling." Here, we demonstrate tha t the standard scalar and spinor actions on a d-dimensional manifold are re covered from such actions in the limit of large matrices if their normaliza tions are correctly scaled as the limit is taken.
