OpenOptRootFinder

public OpenOptRootFinder(Term function,
                         java.util.Map<Variable,Term> startingPoint)

Creates a new root finder for the given starting point and the given function

Parameters:

function - a function

startingPoint - the starting point

OpenOptRootFinder

public OpenOptRootFinder(java.util.List<Term> functions,
                         java.util.Map<Variable,Term> startingPoint)

Creates a new root finder for the given starting point and the given (multi-dimensional) function

Parameters:

functions - a list of functions

startingPoint - the starting point

Method Detail

getOpenOptCode

public java.lang.String getOpenOptCode()
