Hi,
I have two columns of
  1. year and month data
  2. sand data
The year and month data looks like this 199701, so I want to make a column for the month 01 and a seperate column for the year 1997.
How will I seperate this.

Hello, you can run the follow example, using num2str to create a string, choose specific element of your vector and then go back with str2num.
x = [199701 199702]' % your time vector yyyyday
x = num2str(x)
year = x(:,1:4)
day = x(:,5:end)
year = str2num(year)
day = str2num(day)
year =
1997
1997
day =
1
2

Perfect, thank you. So I see you can do it individually, but how will I change that for the entire first column of my data. Seperating the first oclumn into two (month and year)
