Extract numeric year from string
显示 更早的评论
Need to complete the implementation of the date2Year function, which extracts the numeric 4-digit year value from a date string, such as might be returned by the Matlab date() function.
Input variable: str (string containing date to be tested)
Output variable:Year (The numeric year-part of the date)
Script is to begin with: function year = date2Year( str )
Also suggested functions that can be used is str2num() or str2double()

datestr = date;
year = str2num(datestr(end-3:end));
