> Currently, in many cases, a DRM must be read to compute its dimensions when a user calls nrow or ncol. This also implicitly caches the corresponding DRM.
> In some cases, the user actually knows the matrix dimensions (e.g., when the matrices are synthetically generated, or when some metadata about them is known). In such cases, the user should be able to specify the dimensions upon creating the DRM and the caching should be avoided.
