+ ** The datevec function has been extended for better Matlab compatibility.
+    It now accepts string inputs in the following numerical formats: 12, 21,
+    22, 26, 29, 31.  This is undocumented, but verifiable, Matlab behavior.
+    In addition, the default for formats which do not specify a date is
