From matrix to timetable

I have a matrix bb (class:double), where the first column is the time in numeric format. I want to convert this matrix to a timetable:

I can do it with this line:

zz=array2timetable(bb(:,2:end),'RowTimes',datetime(bb(:,1)','ConvertFrom','excel'))

But to me does not look optimal as I have to do it for several long matrices inside an array. Is there a better way to do so?

I think what you have there is about as efficient as you can get.

One minor optimization, to reduce typing, would be to make that into a function or an anonymous function. That would at least save you having to retype the parameters to array2timetable repeatedly.

makeTT = @(x) array2timetable(x(:, 2:end), ...
                              'RowTimes', x(:, 1), ...
                              'ConvertFrom', 'excel');
                          
y1 = makeTT(x1);
y2 = makeTT(x2);
% etc
