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