Given a birth date x, find my age when my birth day will fall on the same day as I was born. So if I was born on Monday, what age will I be when my birthday once again falls on a Monday.

The answer for '29-Feb-1970' should probably be NaN

To solve the issue with the birthday year that falls on '29-Feb-1970' (and all such leap years), use the MATLAB function datestr(x) in place of x in the regexprep while condition loop to convert such b'day years to the correct '01-Mar-1970'. P.S. You can then delete the cheating section and at least get a Cody score of 26.

THX,man. But I did not know datestr have this useage. at that time I just thought this problem is flawed.and not consider this code is cheated.

PS: like the function you use( not gonna tell it for spoil-free), it is actully nice.
