Ran in:
Hello everyone,
I should position higher the data (see for) in which you can see the error; how can I solve this problem?
And how can I remove the spikes?
Thank you very much.
load('giulia_TT.mat')
giulia_monthly=retime(giulia_TT,'monthly','mean');
load('giulia_monthly_DELTA');
E = giuliamensile.Height
E = 254×1
NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN
NEW_6=E *0.35 *10;
% c=giuliamensile{:,1};
% c=datetime(c,'InputFormat','MM-yyyy');
plot(giulia_monthly.Time,NEW_6(:,1),'g-^' ,'MarkerEdgeColor','k','MarkerFaceColor','g') ;
hold on
A=giulia_monthly
A = 254×6 timetable

Subscripting into a table using one subscript (as in t(i)) is not supported. Specify a row subscript and a variable subscript, as in t(rows,vars). To select variables, use t(:,i) or for one variable t.(i). To select rows, use t(i,:).
plot(giulia_monthly.Time(:,1),A);

For removing the spikes, I would recommend looking into the function filloutliers. Since your data isn't meant to be terribly consistent, you will likely need to use a windowed approach, which is further detailed in its documentation.
For your plotting error, you are attempting to index into a table without specifying where on the table you wish to index into. I'm not sure what part you're trying to access, but you should be using methods found here.
Cheers,
