Description

DVextr_ scalar extracts a single scalar data element from a vector component of a field with Node_Data.([a, b, c]) --> select second vector element --> (b)

Input

&in

A reference to a field with Node_Data. The Node_Data can contain only one component. (See DVextract_comp to obtain a single component.) This component can be scalar or vector.

component

An integer. Establishes which sub-component of the component to extract.

Output

out

A new Node_Data object that contains only the extracted scalar data.
