Hello, i have a datetime table A(2000,1) and a second one B(500,1). I want to search at table B if there is a date from table A or if there is the next day. If the condition is met i put in a third table with the name flag the value 1. I have tried this:

for i=1:length(A)

if A(i,1)==B(:,1) || A(i,1) +caldays(1)==B(:,1)

flag(i,:)=1;

end

But i have the error 'Operands to the || and && operators must be convertible to logical scalar values'

Any idea?

The result of the operation

A(i,1)==B(:,1)

is a vector, as is the result of the other equality check you do. You can only use || to compare scalars -- just as the error says. Instead, I think you want

any(A(i,1)==B(:,1) | A(i,1) +caldays(1)==B(:,1))

which will evaluate to true if any of the elements of B match up as you want.
