Detailed Description

This implements a dynamic matrix when we have a limit on the number of "interesting rows".

This version inherits from ClpPackedMatrix and knows that the real matrix is gub. A later version could use shortest path to generate columns.

Constructor & Destructor Documentation

ClpDynamicMatrix::ClpDynamicMatrix  ) 
 

Default constructor.

ClpDynamicMatrix::ClpDynamicMatrix ClpSimplex model,
int  numberSets,
int  numberColumns,
const int *  starts,
const double *  lower,
const double *  upper,
const int *  startColumn,
const int *  row,
const double *  element,
const double *  cost,
const double *  columnLower = NULL,
const double *  columnUpper = NULL,
const unsigned char *  status = NULL,
const unsigned char *  dynamicStatus = NULL
 

This is the real constructor.

It assumes factorization frequency will not be changed. This resizes model !!!! The contents of original matrix in model will be taken over and original matrix will be sanitized so can be deleted (to avoid a very small memory leak)

virtual ClpDynamicMatrix::~ClpDynamicMatrix  )  [virtual]
 

Destructor.

ClpDynamicMatrix::ClpDynamicMatrix const ClpDynamicMatrix  ) 
 

The copy constructor.

ClpDynamicMatrix::ClpDynamicMatrix const CoinPackedMatrix &   ) 
 

The copy constructor from an CoinPackedMatrix.
