date = EcoTotemBroadwayBicycleCount(:,1);
DateTime = table2array(date);
FMTDate = datetime(DateTime,'InputFormat','MM/dd/yyyy HH:mm:ss a');
CyclistAmt = EcoTotemBroadwayBicycleCount(:,5);
DateNum = datevec(FMTDate);
DateNum(:,7) = [0];
A = table2array(CyclistAmt);
DateNum(:,7) = [A];
idx = DateNum(:,1)==2017;
Year2017 = DateNum(idx,:);
i = 1;
for i = 1:1:12
inx2 = Year2017(:,2)==i;
JtD2017 = Year2017(inx2,:)
JtD2017Cyl =JtD2017(:,7);
MonthlyData2017(i) =sum(JtD2017Cyl);
Med2017(i)= median(JtD2017Cyl);

I wonder why you still get the same error. It seems you are converting data to table and then back to array data. May be you need to check dimensions of variables when the data is reformatted during conversions

For some reason you removed all the comments, as I'm sure were in there as all professional programmers put them in. Maybe you could add the comments back in. But it looks like you are trying to get some kind of group statistics. So for that I'd recommend not doing that loop but use one of the functions: splitapply, groupsummary, or grpstats.
