Hi

How to go to previous step while debugging in matlab just like we use F10 for next step? Is there any such option?

Thanks - Lalan

Fellowship PS is crucial in showcasing our passion for a particular field. With the help of our professor and fellow classmates, I was able to create compelling fellowship personal statements that truly reflects my motivation for pursuing this fellowship.

You would think it would be something easy to implement in a interpreted language, but unfortunately, it's not possible to move the execution pointer to an arbitrary line in matlab.

You can only step forward I'm afraid.

Actually, what I really miss is the ability to skip (as in not execute) a line.

I just came across this today debugging some code, arrived on a line which contained a typo (wrong variable name). I could just have typed the correct instruction in the command window and skipped to the next line instead of restarting the debugging from scratch.

It's the same concept though: give the user the ability to move the execution pointer around.

This capability is called "edit and continue". I love it in Visual Studio and am frustrated it's not there in MATLAB. I use Walter's method of doing/undoing stuff in the command window while at a breakpoint.

Not sure if it will help you since i don't know why you need to go back, but have a look at conditional breakpoints. This helped me a lot in the cases where i wanted to go back one step in debugging.

Thanks Hoek for the answer. I felt this necessity here. While debugging a program, I accidentally crossed a function where I needed to go inside that function. So I wanted to come back to previous step and step into that function.
