dataset class -

Arrays for statistical data

Description

Dataset arrays are used to collect heterogeneous data and metadata including into a single container variable. Dataset arrays can be viewed as tables of values, with rows representing different observations and columns representing different measured variables. Dataset arrays can accommodate variables of different types, sizes, units, etc.

Construction

dataset
