Dear guys! I'm struggling to solve this dummy issue. Here it is my code:

if Inan> Istart && (Inan<Iend || isempty(Iend)==1)
    Iend=Inan - 1; 
end 

the error is : Operands to the logical and (&&) and or (||) operators must be convertible to logical scalar values.

Thanks in advance!

If Iend is empty then Inan<Iend is empty and you would be trying to use (empty || something) but operands for || must be scalars.

You should test for empty before testing <

Note: you can use just isempty(Iend) instead of isempty(Iend)==1
