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

Updates two arrays for steepest.

◆ operator=()

AbcMatrix3& AbcMatrix3::operator= ( const AbcMatrix3 )

◆ sortBlocks()

void AbcMatrix3::sortBlocks ( const AbcSimplex model)

◆ swapOne()

void AbcMatrix3::swapOne ( const AbcSimplex model,
const AbcMatrix matrix,
int  iColumn 
)

Swap one variable.
