Element-wise multiplication for timetables

With elimination of fints, how can we do element-wise multiplication (.*) for two timetables?

Thank you!

A timetable can contain many different types of data, some of which define element-wise multiplication and some of which don't. The easiest way to perform arithmetic on a specific numeric variable in a timetable is to index into the timetable.

thedates = datetime('today')+days(0:5);
TT = array2timetable(magic(6), 'RowTimes', thedates)
y = TT.Var3 .* TT.Var5

If you want to perform the same operation on all numeric variables in your timetable you can do that using vartype.

y2 = TT{:, vartype('double')}.^2
TT{:, vartype('double')} = y2

If the data stored in the timetable can be concatenated into a numeric array, you could reference all of it at once.

TT.Variables = sqrt(TT.Variables)
