Syntax b1 | b2 or(b1, b2) Description b1|b2 performs the logical OR operation between the corresponding elements of b1 and b2; the result is false (logical 0) if both operands are false or 0, and true (logical 1) otherwise. or(b1,b2) is equivalent to b1|b2. It can be used to redefine this operator for objects. Example [false, false, true, true] | [false, true, false, true] F T T T See also operator &, xor, operator ˜, operator ||, any Operator || Or with lazy evaluation. Syntax b1 || b2 Description b1||b2 is b1 if b1 is true, and b2 otherwise. Like with if and while statements, b1 is true if it is a nonempty array with only non-zero elements. b2 is evaluated only if b1 is false. b1||b2||...||bn returns the last operand which is true (remaining operands are not evaluated), or the last one. Example Boolean value which is true if the vector v is empty or if its first element is NaN: isempty(v) || isnan(v(1))
