Unless you're using a version of MATLAB older than about R2015a, use readtable, not xlsread. In recent versions, you'll get a datetime variable in the table automatically. In less recent versions, you'll get either a numeric (Excel serial date numbers) or a text variable in the table, depending on how the cells in the spreadsheet are formatted. In either case, call datetime on that table variable to get a datetime variable. For Excel date numbers, use 'ConvertFrom','excel'.

I get the error "Attempt to reference field of non-structure array."
