Is it possible to 'clear all' variables except one?

I am using clear all command. But I wan to keep just one of the varibles. Lets say the name of that variable is 'var'.

clearvars -except var

No, that is not possible using "clear all"

The only time you should ever use "clear all" is if you are deliberately resetting your entire MATLAB session. If it would not be acceptable to quit and re-enter MATLAB at that point then you should not use "clear all"

You should have a look at the clearvars() command, which does have an -except option.

Another method is the FEX keep utility:
