I am trying to create a configuration panel containing some configurable parameters. The configuration value shall be used in other Matlab functions. But,when I enter the variable name ("Value")to the command window, Matlab notifies the variable is not defined.
function edit1_Callback(hObject, eventdata, handles)
Value = get(handles.edit1,'String');
Value = str2double(Value);
Could you please give me your advise? Many thanks

You can use "uisave" command to save the variable to .mat file. Load the .mat file to use the variable.
