I have a table T that has a first column called "Dates" which contains the observation dates for input variables into a model and I run the model and generate output called "yfit1". How can I create a new table M which contains the Dates from T and the model output yfit1?

在 MATLAB Online 中打开

Something like this:

% Sample data
T = table(datetime('now')+(0:2).', rand(3,1), ...
    'VariableNames', {'Dates', 'Something'});
yfit1 = rand(3,1);
% Create new table
M = table(T.Dates, yfit1, 'VariableNames', {'Dates', 'Fit'});

It may be that you don't want to create a new table. If the dates are all the same, then it seems like there's a 1:1 correspondence between inputs and outputs. Why not just add a new variable to your existing table? Better yet, create a timetable containing your inputs and output(s).
