The indicated statement always returns false or results in an error. This is
because the statements A && B and A ||
B always either return a logical value or throw an error.
Rewrite the code to perform the logical operation outside of the indicated function.
For example, to determine whether both a and
b are empty:
a = 1;
b = 2;
isnan(a) && isnan(b)To determine whether a is empty, and then determine the
logical AND of the result and b:
a = 1;
b = 2;
isnan(a) && b
