java.lang.Object

org.ojalgo.matrix.store.operation.MatrixOperation

org.ojalgo.matrix.store.operation.HermitianRank2Update

public final class HermitianRank2Update
extends MatrixOperation

[A] -= ([a][b]^c+[b][a]^c)
[A] is assumed to be hermitian (square symmetric) [A] = [A]^C.
^C == conjugate transpose
