Common Mistakes

Using | instead of & for AND operation.

Using && which only works for scalars, not arrays.

The & operator performs element-wise logical AND in MATLAB.

💡 Hint

Common Mistakes

Using ! which is not valid in MATLAB.

Using - or ^ which are arithmetic operators.

The ~ operator negates logical values element-wise in MATLAB.

4fill in blank

hard

Fill both blanks to create a logical expression that is true when A is true and B is false.

MATLAB

result = A [1] [2] B;

Drag options to blanks, or click blank then click option'

A&

C~

D&&

💡 Hint

Common Mistakes

Using | instead of & for AND.

Not negating B correctly.

Use & for AND and ~ to negate B, so the expression is true only if A is true and B is false.

5fill in blank

hard

Fill all three blanks to create a logical expression that is true when either A or B is true, but not both.

MATLAB

result = (A [1] B) [2] ~ (A [3] B);

Drag options to blanks, or click blank then click option'

A&

B|

C~

💡 Hint

Common Mistakes

Using incorrect operators that don't produce XOR behavior.

Misplacing negations.

This expression uses OR and AND with negations to create an XOR-like behavior: true if A or B is true, but not both.
