What is the difference between the effect of clear and clearvars?

Best Answer

clearvars just clears variables you specify, in the way you specify.

clear is more powerful in the sense you can clear variables, variables, functions, compiled scripts, MEX-functions

See doc clearvars:

clearvars -except keepVariables

I recommend to use functions. Then there is no need to clear workspace variables. For larger projects it is very useful, if the workspace is kept clean, instead of applying method to clean them manually.

MATLAB: What is the difference between clear and clearvars

In those simplest forms I don't think there is any difference. Both have extended arguments though that make them different, especially clear which obviously also extends to clearing cached functions, mex functions and other stuff.
