Having some trouble w/ my data.

The dates are showing up wrong. For example:

3/9/9102

3/10/9102

Obviously, i didn't collect data in 9102 and if you read it backwards, its 2019 which would be the correct date.

Does anyone know how to correct for this?

For example, how would you convert

3/9/9102 --> 3/9/2019

If someone knows, let me know. Thanks

Hi SS,

From my understanding of your question,you want to reverse the year part of the date.Im assuming that the dates are in the string format.The following code snippet might help,

date='3/9/9102';
arr=split(date,'/');
arr(3)=reverse(arr(3));
date=char(join(arr,'/'));

Thanks a lot for responding!

The code does work for one variable, but unfortunately, when its in a column, I keep getting this error message:

"Error using split

First argument must be text."

For example,

%Generate data
dates = ['3/11/9102'; '3/12/9102'; '3/13/9201'; '3/14/9102'];
%Fix backwards year
splitter = split(dates,'/');
Error using split
First argument must be text.
splitter(3) = reverse(splitter(3));
dates_new = char(join(splitter,'/'));
