NA_options

 

Data Structure: NA_options

Description

NA inversion algorithm control data

Usage

NA_options     NUM=ival   where ival  is the data structure number

 

Description

Overview

The NA_options data structure defines the control options for the nearest neighbour inverse identification algorithm, also known as the Neighbourhood Algorithm (NA).
