why am I getting error "Undefined function or variable"

I have defined a variable called "bestDimen". There is no error. I crosschecked many times. The script is also correct. It was working fine. But all of a sudden it starts giving following error.

"Undefined function or variable 'bestDimen'."

I am using "Matlab 2017a" Please reply fast. It's very urgent. I need help

share your code, it easy to answer the problem exactly.

"all of a sudden" - you can be sure, that this happens, because you instruct Matlab explicitly to delete the variable.

Without seeing the code, all I can do is guessing. I guess, that you are using scripts and any of the scripts contain a clear, clear vars or even worse a clear all statement.

Using scripts for productive work is a bad programming practice. Prefer functions, because they avoid polluting the workspaces and in consequence no clear 'ing is need.

Thank you all for replying me so fast and early. The problem is solved when I restarted my computer and then Matlab started doing everything once again. Thank you so much to all of you. I appreciate your support.
