Lower norms

Store the lower norms (i.e., \(\| x_1 \|_2\), where the member of the subcone is \((\chi_0;x_1)\)) of each subcone and store the norm within the root entry of said subcone.

Note

The cutoff parameter only effects parallel performance and is used to decide whether a subcone is sufficiently large to be treated separately.

void soc::LowerNorms(const ElementalMatrix<Real> &x, ElementalMatrix<Real> &lowerNorms, const ElementalMatrix<Int> &orders, const ElementalMatrix<Int> &firstInds, Int cutoff = 1000)

void soc::LowerNorms(const DistMultiVec<Real> &x, DistMultiVec<Real> &lowerNorms, const DistMultiVec<Int> &orders, const DistMultiVec<Int> &firstInds, Int cutoff = 1000)
