The xlswrite function can write the contents of a cell array to a spreadsheet.  A manufacturer kepts information on the weights of some parts in a cell array.  Every row stores the part identifier code followed by weights of some sample parts.  To simulate this, make the following cell array:

>> parts = {'A22', 4.41 4.44 4.39 4.39
                 'Z29', 8.88 8.95 8.84 8.92}

Then, write this to a spreadsheet file.
