Basically, I have a table with dates that are currently char's and I want to convert them into datetime format. This is how the dates are now:
'2/4/22'
'2/5/22'
'2/6/22'
The problem is that these dates conflict with another dataset where the dates are like this:
2/4/22
2/5/22
2/6/22
I'm trying to make the dates appear the same for both tables and this was the command I ran:
Data.StudyDate_converted = cellfun(@(x) datetime(x), Data.StudyDate, 'UniformOutput', false);
This isn't doing the trick. The new column that the table creates in the table shows a 1x1 date time in each cell and when you click on it, the date reads as 04-Feb-0022
If someone knows a fix, please let me know. I attached the dataset that I want to convert from a char to datetime to this post in case its needed. The specific variable I want to convert from char to datetime is "StudyDate".
Thanks in advance
