class ROOT::Minuit2::MnApplication

    application interface class for minimizers (migrad, simplex, Minimize,
    User normally instantiates the derived class like ROOT::Minuit2::MnMigrad
    for using Migrad for minimization

Function documentation

virtual ~MnApplication()
{ }
FunctionMinimum operator()(unsigned int maxfcn = 0, double tolerance = 0.1)
      Minimize the function
      @param maxfcn : max number of function calls (if = 0) default is used which is set to
                     200 + 100 * npar + 5 * npar**2
      @param tolerance : value used for terminating iteration procedure.
             For example, MIGRAD will stop iterating when edm (expected distance from minimum) will be:
             edm < tolerance * 10**-3
             Default value of tolerance used is 0.1
