That is, expr2 is not evaluated if expr l is logical 1(true). Each expression must evaluate to a scalar logical result Examples Use scalar logical Conditions Create two vectors X=[1011]; Y=[00⑧66]; Using the short-circuit or operator with X and y returns an error. The short-circui operators operate only with scalar logical conditions Use the any and all functions to reduce each vector to a single logical condition any (X) any(Y) 1-2 Logical Operators: Short-Circuit & l ans= logical The expression is equivalent to 1 OR 0, so it evaluates to logical l(true) after computing only the first condition, any(X) Specify Dependent Logical Conditions Specify a logical statement where the second condition depends on the first. In the following statement, it doesn't make sense to evaluate the relation on the right if the divisor, b, is zero b=1; a=20 X=(b~=0)(a/b>18.5) X= Logica The result is logical l(true). However, if(b-=0)evaluates to false, MATLABB assumes the entire expression to be false and terminates its evaluation of the expression early Specify b =0 and evaluate the same expression b=0 X=(b~=)s(a/b>18.5) x= logical The result is logical 0 (false). The first statement evaluates to logical o (false), so the expression short-circuits 13 Alphabetical List Change structure Field value Create a structure with fields named ' file'and Format s=struct(File, I'myGraph','Format',[1) S= struct with fields File: 'my Graph Format: Short-circuit expressions are useful in if statements when you want multiple conditions to be true. The conditions can build on one another in such a way that it only makes sense to evaluate the second expression if the first expression is true pecify an if statement that executes only when S contains an empty field named Format if isfield(s,'Format )& isempty(. Format) S Format =.png end s= struct with fields File: ' myGraph Format:.png The first condition tests if format is the name of a field in structure S. The second statement then tests whether the Format field is empty. The truth of the second condition depends on the first. The second condition can never be true if the first condition is not true. Since S has an empty field named 'Format the body statement executes and assigns S Format the value.png Definitions Logical Short-Circuiting With logical short-circuiting, the second operand, expr2, is evaluated only when the result is not fully determined by the first operand, expr1
