**Course Title:** MATLAB Programming: Applications in Engineering, Data Science, and Simulation **Section Title:** MATLAB Control Structures **Topic:** Break and continue statements In the previous topics, we explored various control structures in MATLAB, including conditional statements (if-else, switch-case) and looping structures (for, while, nested loops). In this topic, we'll focus on two essential statements that aid in manipulating the flow of loops in MATLAB: break and continue statements. **What are break and continue statements?** * **Break Statement:** The break statement is used to terminate the execution of a loop prematurely. It stops the loop entirely and continues execution from the statement after the loop. * **Continue Statement:** The continue statement skips the remaining code inside a loop for the current iteration and moves to the next iteration. ### Break Statement in MATLAB **Syntax:** ```matlab break ``` When the break statement is encountered within a loop, the loop execution stops immediately, and the control is transferred to the statement following the loop. **Example 1: Using the break statement in a for loop** ```matlab for i = 1:5 if i == 3 break end disp(i) end disp('Loop terminated') ``` Output: ``` 1 2 Loop terminated ``` In this example, the loop iterates over numbers 1 to 5. When `i` equals 3, the break statement is executed, terminating the loop. The remaining numbers are not displayed. **Example 2: Using the break statement in a while loop** ```matlab i = 1; while i <= 5 if i == 3 break end disp(i) i = i + 1; end disp('Loop terminated') ``` Output: ``` 1 2 Loop terminated ``` Similar to the previous example, the break statement is used to terminate the while loop when `i` equals 3. ### Continue Statement in MATLAB **Syntax:** ```matlab continue ``` When the continue statement is encountered within a loop, the remaining code inside the loop is skipped for the current iteration, and the loop moves to the next iteration. **Example 3: Using the continue statement in a for loop** ```matlab for i = 1:5 if i == 3 continue end disp(i) end ``` Output: ``` 1 2 4 5 ``` In this example, the loop iterates over numbers 1 to 5. When `i` equals 3, the continue statement is executed, skipping the display of 3. The remaining numbers are displayed. **Example 4: Using the continue statement in a while loop** ```matlab i = 1; while i <= 5 if i == 3 i = i + 1; continue end disp(i) i = i + 1; end ``` Output: ``` 1 2 4 5 ``` Similar to the previous example, the continue statement is used to skip the display of 3 in the while loop. ### Practical Takeaways and Tips * Use break statements to terminate loops when certain conditions are met. * Use continue statements to skip certain iterations within loops. * Be cautious when using break and continue statements, as they can make code difficult to read and understand if not properly commented. ### Key Concepts to Remember * Break statement: Terminates loop execution. * Continue statement: Skips the remaining code inside a loop for the current iteration. **Additional Resources:** * MATLAB Documentation: [Break Statement](https://www.mathworks.com/help/matlab/ref/break.html) * MATLAB Documentation: [Continue Statement](https://www.mathworks.com/help/matlab/ref/continue.html) **We would love to hear from you** - Do you have any questions regarding break and continue statements in MATLAB?
