Comparison operators in MATLAB - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the == operator do in MATLAB?

The == operator checks if two values are equal. It returns true if they are the same, and false if they are different.

beginner

What is the difference between = and == in MATLAB?

= is used to assign a value to a variable, while == is used to compare two values for equality.

beginner

What does the ~= operator mean in MATLAB?

The ~= operator means "not equal to". It returns true if the two values are different, and false if they are the same.

beginner

How do you check if one number is greater than another in MATLAB?

Use the > operator. For example, 5 > 3 returns true because 5 is greater than 3.

beginner

What does the <= operator do in MATLAB?

The <= operator checks if the value on the left is less than or equal to the value on the right. It returns true if it is, otherwise false.

What will 3 == 3 return in MATLAB?

A false

B true

C 3

D Error

The == operator checks if two values are equal. Since 3 equals 3, it returns true.

Which operator checks if two values are NOT equal in MATLAB?

A !=

B ==

C ~=

D =

In MATLAB, ~= means "not equal to". The != operator is not used in MATLAB.

What does 5 <= 2 return?

A false

B true

C 5

D Error

5 is not less than or equal to 2, so 5 <= 2 returns false.

Which operator is used to assign a value to a variable in MATLAB?

A =

B ~=

C >

D ==

The = operator assigns a value to a variable, for example x = 5.

What will 7 > 10 return?

A true

B Error

C 7

D false

Since 7 is not greater than 10, the expression returns false.

Explain how to use comparison operators in MATLAB to compare two numbers.

Think about how you check if numbers are equal or different.

Describe the difference between assignment and comparison operators in MATLAB.

One sets a value, the other checks if values are the same.
