i need to run some scripts inside a loop in order to make a parametric study on some variables inside the scripts. At each iteration i need to change the input variables for the script, save the variables of interest in an array and clear all the others.

Write functions instead of scripts, then this task will be trivial.

Hello Domenico,

You can use the clearvars command, with the -except option, to clear all the variables except the ones you need. You will have to specify the required variables by using either their names or regular expressions (with the -regexp option).

For more details and examples, refer to the attached MATLAB documentation page.
