I have 5 coloumn data consist year, month, date, hour and elevation data. I want to merge the data into two coloumn so it become:
coloumn1(datetime) coloumn 2
YYYY-MM-DD HH:mm:ss Elevation Data
I have tried some examples from matlab forum, but it not work. I used 2016b matlab version. Can anyone help me? Thank you.

The best way to combine data types (datetime and numeric) is to use a table. There are several possible approaches. Here is one.
data = readmatrix("tidal data.txt");
Date = datetime(data(:,1:3)) + hours(data(:,4));
Elev = data(:,5);
T = table(Date,Elev);
T.Date.Format = 'yyyy-MM-DD HH:mm:ss'
