merging multiple timetable using for loop

4 次查看(过去 30 天)
Hi all,
i am trying to merge multiple timetables using the code 'outerjoin' and 'for loop'.
Amongst many timetables that are imported from a folder, there are (may exist) empty timetables inbetween.
The existence of each timetable data types are checked and then organized as an array to merge them using 'for loop'.
if exist ('timetable_csv') % checking whether timetable data exist
timetable_{1} = timetable_csv
end
Below is the 'for loop' iteration, which should at the end 1) disregard non-existing timetables and 2) merge all existing timetables.
As i ran this code, error message came stating "Error using tabular/outerjoint. A and B must be tables"
numtimetable = length(timetable_)
for h = 1:numtimetable
timetable = timetable_{h}
for hh = 2:numtimetable
timetable = outerjoin(timetable,timetable_{hh})
end
end
Thus i tried to change the variable 'timetable_{ }' cell array to timetable, as 'timetable' was ok.
numtimetable = length(timetable_)
for h = 1:numtimetable
timetable = timetable_{h}
for hh = 2:numtimetable
table_c2t{hh} = cell2table(timetable_{hh})
timetable_t2tt{hh} = table2timetable(table_c2t_{hh})
timetable = outerjoin(timetable,timetable_{hh})
end
end
However, another message appeared stating, "Error using cell2table. Cell must be 2-D cell array".
I would appreciate if you could advise me how to restructure the code so that i may merge multiple titmetable using the example presented above.
Of course, merging them using other possible coding is welcome as well.
thanks.

i am defining all the tables (ex. timetable_csv) in "timetable_".

You define timetable_ as timetable_csv. Where/how do you define timetable_csv?
