Code runs without workspace variables appearing

I'm encountering various issues with my matlab programming. For example I can run my script, but the workspace will remain blank. Occaisionally, I will be told that the expresson on the left of an equal sign is invalid, even when its a rather standard variable name such as BridgeNum. On other occasions I will get an error on my script telling me that 'if' is an invalid use of a reserved word, despite that very same code functioning perfectly before I added a csvwrite command. I believe my program must have gotten infected with some kind of malware, but I dont know how to identify it or how to rectify it.

This question is way too vague for us to answer. Please post a specific example of code that is not working for you, along with a copy & paste of the entire error message.

"Occaisionally, I will be told that the expresson on the left of an equal sign is invalid, even when its a rather standard variable name such as BridgeNum."

In my experience, the most common cause of that is that a close ] has been missed.

"On other occasions I will get an error on my script telling me that 'if' is an invalid use of a reserved word, despite that very same code functioning perfectly before I added a csvwrite command."

possibly you missed a close ' on the file name.
