MATLAB Relational Operators

🔍 MATLAB Relational Operators

The result of a relational operation is always logical: true (1) or false (0).
MATLAB is developed by MathWorks.

🔹 List of MATLAB Relational Operators

🧪 Examples with Output

1️⃣ Greater Than (>)

Output

2️⃣ Less Than (<)

Output

3️⃣ Greater Than or Equal (>=)

Output

4️⃣ Less Than or Equal (<=)

Output

5️⃣ Equal To (==)

Output

⚠️ Use == for comparison, not = (assignment).

6️⃣ Not Equal To (~=)

Output

📊 Relational Operators with Arrays (Element-wise)

Output

📌 Each element is compared individually.

⚠️ Important Notes

• Output is always logical

• Works on scalars, vectors, and matrices

• For arrays, operations are element-wise

• Commonly used in conditions and loops

🎯 Interview Questions:

🔹 Q1. What is the output type of relational operators in MATLAB?

Answer: Logical (true or false).

🔹 Q2. Difference between = and ==?

Answer:
= assigns a value, == compares two values.

🔹 Q3. Which operator is used for “not equal to”?

Answer: ~=

🔹 Q4. Can relational operators work on arrays?

Answer: Yes, element-wise comparison is performed.

🔹 Q5. What is the result of 5 > 10?

Answer: false (logical 0).

🔹 Q6. Where are relational operators mostly used?

Answer: In if, while, for loops, and decision making.

🔹 Q7. What does >= mean?

Answer: Greater than or equal to.

✅ Summary

• Relational operators compare values

• Result is always logical

• Works with scalars & arrays

• Essential for control statements
