MATLAB Central Newsreader - cell mode execution

cell mode execution

Is there any way to see where an error is, when ctrl-enter execution in cell mode fails? I like cell mode but I can't use it because it makes debugging impossible, when I just get a popup box saying "the cell cannot be evaluated". How can I get a more informative message? Is this just fixed in a later version? I have 2006b.

Yes, this message isn't very helpful. I think you see it when there is an invalid syntax, i.e. a parse error. If you hit "F5" to run the whole file, does a better error message print to the command window?

Yes I see a helpful message when I use F5. I usually just end up converting the script to a function, which also allows me to see helpful messages. Sometimes I want the added functionality of cell mode though - is there no way to combine cell mode with meaningful error messages?

Thanks

You'd think so! This limitation actually goes deep into the dark corners of MATLAB and reflects architectural decisions that were made a long time ago. It is on our radar, but will take some time to work this out.
