operators must be convertible to logical scalar values

2 views (last 30 days)
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
