CoinIndexedVector dj1,
const double *  piWeight,
double  referenceIn,
double  devex,
unsigned int *  reference,
double *  weights,
double  scaleFactor 
)

Updates two arrays for steepest.

ClpPackedMatrix3& ClpPackedMatrix3::operator= ( const ClpPackedMatrix3 )
void ClpPackedMatrix3::sortBlocks ( const ClpSimplex model)

Sort blocks.

void ClpPackedMatrix3::swapOne ( const ClpSimplex model,
const ClpPackedMatrix matrix,
int  iColumn 
)

Swap one variable.
