Break and continue in MATLAB - Mini Project: Build & Apply

Using Break and Continue in MATLAB Loops

📖 Scenario: You are analyzing a list of daily temperatures to find specific conditions. Sometimes you want to stop checking once a certain temperature is found, or skip days that don't meet a condition.

🎯 Goal: Build a MATLAB script that uses break and continue statements inside a for loop to process temperature data.

📋 What You'll Learn

Create a vector called temperatures with exact values

Create a variable called threshold to set a temperature limit

Use a for loop with continue to skip temperatures below the threshold

Use break to stop the loop when a temperature equals 100

Print the temperatures processed before stopping

💡 Why This Matters

🌍 Real World

Analyzing temperature data to quickly find important values or skip irrelevant data is common in weather monitoring and control systems.

💼 Career

Using <code>break</code> and <code>continue</code> helps programmers write efficient loops that handle real-world data with conditions, a key skill in data analysis and engineering.

1

Create the temperature data vector

Create a vector called temperatures with these exact values: [72, 85, 90, 100, 95, 88]

MATLAB

% Create the vector temperatures with the given values

Need a hint?

Use square brackets to create a vector in MATLAB.

2

Set the temperature threshold

Create a variable called threshold and set it to 80

MATLAB

temperatures = [72, 85, 90, 100, 95, 88];
% Create the variable threshold and set it to 80

Need a hint?

Just assign the number 80 to the variable threshold.

3

Use break and continue in a for loop

Write a for loop using variable i from 1 to length of temperatures. Inside the loop, use continue to skip temperatures less than threshold. Use break to stop the loop if the temperature equals 100. Store processed temperatures in a vector called processed.

MATLAB

temperatures = [72, 85, 90, 100, 95, 88];
threshold = 80;
% Write the for loop with break and continue below

Need a hint?

Use continue to skip adding temperatures below threshold. Use break to stop when temperature is 100.

4

Display the processed temperatures

Write a disp statement to display the vector processed

MATLAB

temperatures = [72, 85, 90, 100, 95, 88];
threshold = 80;
processed = [];
for i = 1:length(temperatures)
    if temperatures(i) < threshold
        continue
    end
    if temperatures(i) == 100
        break
    end
    processed(end+1) = temperatures(i);
end
% Display the processed vector

Need a hint?

Use disp(processed) to show the vector.
