function varargout = txcl(varargin) %TXCL M-file for txcl.fig % TXCL, by itself, creates a new TXCL or raises the existing % singleton*. % % H = TXCL returns the handle to a new TXCL or the handle to % the existing singleton*. % % TXCL('Property','Value',...) creates a new TXCL using the % given property value pairs. Unrecognized properties are passed via % varargin to txcl_OpeningFcn. This calling syntax produces a % warning when there is an existing singleton*. % % TXCL('CALLBACK') and TXCL('CALLBACK',hObject,...) call the % local function named CALLBACK in TXCL.M with the given input % arguments. % % *See GUI Options on GUIDE's Tools menu.
