How to clear workspace from a function?
조회 수: 24 (최근 30일)
I want to create a function that will perform some maintenance operations at the beginning of the script. For example, this function takes a few arguments that will lead to specific initialisations of paths and variables, and above all, clear the workspace from the previous run.
I want to put it in a specific function as the job requires dozens of lines which are quite irrelevant in the work. And I want my "main' script to be as short, readible and high-level as possible.
Below only the first lines of the function.
clearvars -except varargin
However if I do 2 consecutive runs, it does not clear the workspace. If I want to, I need to explicitely write the "clear" command in the main script, which I try to avoid.
Is there any way to do it?
Thanks in advance.

Functions do not keep their variables across calls to them unless a variable is specifically defined in the function using the "persistent" keyword. So, you do not need to try to clear variables in a function workspace in this scenario. Each call to the function has its own variable scope (i.e., workspace), which is already clear when the function starts executing, except of course for the variables that you pass to the function as input arguments.
If the function accesses the variables in the base workspace (using evalin, etc.), that is a different question, in which case you can use the clear command.
