I have a set of data from Jan 2000 to 2011, and I want to calculate mean value of data from Nov of one year to Apr of the next year. How can I do it?

Not sure what is the format of your data. Use function isbetween and below shows an example that you can implement it into your code.
TimeStamps = datetime([2000 11 4; 2001 3 2; 2001 8 15; 2001 10 10;...
2001 12 14; 2002 1 31; 2002 3 25;...
2002 4 29; 2002 12 21; 2003 3 18]);
Profit = [2032 3071 1185 2587 1998 2899 3112 909 2619 3085]';
TT = timetable(TimeStamps,Profit);
tlower = datetime(2000,11,1)+calyears(0:11);
thigher = datetime(2001,4,30)+calyears(0:11);
meanProfit = arrayfun(@(x,y) mean(TT.Profit(isbetween(TT.TimeStamps,x,y))),tlower,thigher)

Do you want the following output?
Or do you want to use function timerange?
TimeStamps = datetime([2000 11 4; 2001 3 2; 2001 8 15; 2001 10 10;...
2001 12 14; 2002 1 31; 2002 3 25;...
2002 4 29; 2002 12 21; 2003 3 18]);
Profit = [2032 3071 1185 2587 1998 2899 3112 909 2619 3085]';
TT = timetable(TimeStamps,Profit);
tlower = datetime(2000,11,1)+calyears(0:11);
thigher = datetime(2001,4,30)+calyears(0:11);
meanProfit = arrayfun(@(x,y) mean(TT.Profit(isbetween(TT.TimeStamps,x,y))),tlower,thigher);
table(tlower',thigher',meanProfit','VariableName',{'Period Start','Period End','Mean'})
