Algorithm (Workflow)

This function, datestrroman, converts a date string into a Roman numeral representation. It is part of the SolidGeometry library and was created by Tim Lueth.

Input Parameters

Output

Algorithm Steps

  1. Initialize S with the current date in 'YYYY-MM-DD' format using datestr(now, 'yyyy-mm-dd').
  2. Check if there is at least one input argument (nargin >= 1). If so, set S to the first input argument.
  3. Verify if S is a character string. If not, convert it to a date string using datestr(S, 'yyyy-mm-dd').
  4. Extract the year, month, and day from the string S using str2num on the respective substrings.
  5. Convert the year, month, and day to Roman numerals using the roman function.
  6. Format the Roman numeral date as a string in the format 'YYYY-MM-DD' using sprintf.

Example Usage

To convert the current date to Roman numerals, simply call datestrroman without any arguments. To convert a specific date, such as '2012-04-03', call datestrroman('2012-04-03').
