Question

1. How do you insert a “break point” in your script?

2. What happens to the execution of a script when MATLAB encounters a break point? Is the execution ended?

3. What happens if a break point is inserted within a loop (like a for loop)?

4. How do you step through different lines of the code during the debugging session?

5. How can you see the values of a particular variable when the debug session is active?

6. Are the variables of a function available in the workspace during normal execution of a script? Does this change when running a script using the debugging mode (i.e. using break points)?

Answer 1

a.

Go the particular line of scrip where you want to put break point and add breakpoint

by clicking on breakpoint >>Set /Clear .

Or Simply go that line and press F12.

2.

If you put break point at a line ,the execution will stop at that line and will continue if you click pn continue.

3.If you put break point in a loop then break point will hit that particular line code as many times as it will satisfy the condition in that loop and execution will stop as many times.

\\

Here for this case ,the break point will hit line 5 as many times if x(i) is greater than 0.2.

4.

If you want to step next line ,just click on step or F10

5.

You can see value of any variable by putting break point to that variable and then bringing cursor to that variable when breakpoint hits that line of code.
