function varargout = OAO_Multi_SVM(varargin)
% OAO_MULTI_SVM M-file for OAO_Multi_SVM.fig
%      OAO_MULTI_SVM, by itself, creates a new OAO_MULTI_SVM or raises the existing
%      singleton*.
%
%      H = OAO_MULTI_SVM returns the handle to a new OAO_MULTI_SVM or the handle to
%      the existing singleton*.
%
%      OAO_MULTI_SVM('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in OAO_MULTI_SVM.M with the given input arguments.
%
%      OAO_MULTI_SVM('Property','Value',...) creates a new OAO_MULTI_SVM or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before OAO_Multi_SVM_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to OAO_Multi_SVM_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
