Variables not appearing in workspace
Show older comments
I created a MATLAB script that should create some variables, and they only appear in the workspace when i use CRTL+C and finish the programm. I dont think that they're availabe in the progress of the program because it doesn´t work the way it should

Have you tried using the debugger?

I bet they are and you just need to view this: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/

Do you know that there are different workspaces? A base workspace, where variables from scripts go, and local workspaces that exist only when a function is being run and vanish once you leave the function.

I have a related problem of variables not appearing in the workspace, but which has nothing to do with functions. If I manually create any variable (like 'test = 5'), it would not be visible in the workspace window. However, if I list variables (using 'who' or 'whos') all variables would show up. I never had this problem before, only after updating to Matlab 2017b.
I definitely think this is a bug or me misunderstanding some newly released functionality. I have tried re-installing Matlab, which helped at first. But eventually the problem returned after a few Matlab sessions (Not sure if this is somehow related to the debug mode?).
Any ideas welcome. Thanks.

Where (in what context) did you "manually create any variable"? Describe in more detail exactly what you did to create that variable.

Do you have Windows? If so, you can run PSR to take screenshots. Type PSR in the search window to find it. Under Windows 10, typing in PSR will show"Steps Recorder" and you can run that to record all the screenshots as you do a series of things in MATLAB. Then save the recording and upload it here.

I have this problem too, my script has no functions called other than mat labs own functions, and many variables are not showing up in the workspace. Will try and roll back to 2017a until this is fixed.

Why is no one using psr to show us screen captures? It does not good if you just same "same here" - that does not give me any information to try to help you.

Also seems to depend on scoping, so a variable defined inside of a for loop for example, will not show up in the workspace afterwards (even though the iterator value is, assuming it hasn't been cleared).
Try defining outside of a dedicated scope like a loop or function.
