Hi to all
I have data in file h172.csv
I write the code to open this
>clear
>load h172.csv
>[~, txt] = xlsread('h172.csv');
> JOPR_cells = regexp(txt(1:end),',', 'split');
>JOPR_cell =vertcat(JOPR_cells{:});
>JOPR = str2double(JOPR_cell);
>y = JOPR(:,1); % years
>m = JOPR(:,2); %months
>d = JOPR(:,3); %days
>h = JOPR(:,4); %hour
>sl = JOPR(:,5); %sea level (WL)
i want to rearrange history time like %formatOut = 'dd/mm/yyyy HH:MM:SS'; (Datatime) and in to Julian time (jday)
the table finaly example like this.

How about the following?
% Read the csv file
D = dlmread('h172.csv');
% Generate datetime vector
Time = datetime(D(:,1),D(:,2),D(:,3),D(:,4),0,0);
% Change display format
Time.Format = 'dd/MM/yyyy HH:mm:SS';
% Calculate julian date
Jday = juliandate(Time);
% Extract WL
WL = D(:,5);
% Arrange them to a table variable
T = table(Jday,Time,WL);

Oh, that's because the function 'datetime' was introduced in R2014b.
A simple and better solution is to upgrade your MATLAB. Otherwise, we have to think about other solution...
