Class DComplexPlusMult

java.lang.Object
  extended by cern.jet.math.tdcomplex.DComplexPlusMult
All Implemented Interfaces:
DComplexDComplexDComplexFunction

public class DComplexPlusMult
extends Object
implements DComplexDComplexDComplexFunction

Only for performance tuning of compute intensive linear algebraic computations. Constructs functions that return one of

a and b are variables, constant is fixed, but for performance reasons publicly accessible. Intended to be passed to matrix.assign(otherMatrix,function) methods.
