% This script collects the data used in stateflow charts in the currently
% selected simulink model and saves it into an excel file with the
% sheetname same as the model name. Multiple model data can be saved into a
% single excel file using the different sheetname. Also if the data values
% are loaded in the matlab base workspace, it will be listed along with the
% variable name. If the data value is not present in the workspace, the value
% field will be filled by 'Undefined'. The data listed in the excel file are
% sorted in alphabetical order of variable names.
