FrameViewAsColumnsT Method |
Exposes a list of columns of uniform type.
Namespace: Meta.Numerics.Data
Assembly: Meta.Numerics (in Meta.Numerics.dll) Version: 4.1.4
SyntaxType Parameters
- T
- The type of the data.
Return Value
Type: IReadOnlyListIReadOnlyListTA column-oriented, read-only collection of all the data in the view.
RemarksSome methods, such as MeansClustering(IReadOnlyListIReadOnlyListDouble, Int32) and PrincipalComponentAnalysis(IReadOnlyListIReadOnlyListDouble), require their inputs as column-oriented array of uniform type. This method exposes the view as such a collection.
RemarksThis operation is both time and memory efficient. It does not copy every element into a new collection, but instead simply instantiates a converter that implements the list operations directly against the already existing storage.
