Eq.Data is a struct with 2 fields
data is 5864x1 datetime
R1 is 1x27 double
i want to create the follow array:
TradeF(1)=Eq.Data(738)   (because r1(1) = 738 )
TradeF(2)=Eq.Data(734)   (because r1(2) = 734 )
...
i try to use arrayfun but i but not so use it correctly
    
T.TradeF=arrayfun(@(s,i)s.data(i),Eq,r1)'; 
i receive this error:
Error using arrayfun
All of the input arguments must be of the same size and shape.
Previous inputs had size 1 in dimension 2. Input #3 has size 27
