Class ConcatenatedLPModelColumns

java.lang.Object
  net.sourceforge.combean.mathprog.lp.model.AbstractLPModelComponent
      net.sourceforge.combean.mathprog.lp.model.ConcatenatedLPModelColumns

All Implemented Interfaces:

AbstractMatrix, LPModelColumns, LPModelComponent

public class ConcatenatedLPModelColumns
extends AbstractLPModelComponent
implements LPModelColumns

A columnwise LP model component which consists of a set of columnwise LP model components which are joined rowwise. This means that the first column of the first subcomponent is concatenated with the first column of the second subcomponent etc. to make up the first column of the joint component). The concatenated components must have distinct row offset ids. These will be retained by the composite object. The column offset ids are taken from the component with the highest number of columns and the mapping to the model index for a given local id must be indentical for all internal components.

Constructor Summary

ConcatenatedLPModelColumns()
