This is the development version of ScaledMatrix; for the stable release version, see ScaledMatrix.

Creating a DelayedMatrix of Scaled and Centered Values

Bioconductor version: Development (3.19)

Provides delayed computation of a matrix of scaled and centered values. The result is equivalent to using the scale() function but avoids explicit realization of a dense matrix during block processing. This permits greater efficiency in common operations, most notably matrix multiplication.
