I've got a problem when using the command websave(url). I receive an error msg that says
"expired, missing or invalid certificates".
Since I have no idea of what it means I tryed to overcome the problem opening the page using web(url) and clicking on the opened page 'save as'.
So I'm asking whether I can avoid this manual activity with some commands that apply to the opened web page in the browser.
Thx

Hi Fillipo,
In order to tackle the 'certificates' issue, I would suggest to refer to this community thread: https://www.mathworks.com/matlabcentral/answers/1788360-error-using-websave-certificate-rootcerts-pem-expired-missing-or-invalid
Also it seems you are lacking a parameter while calling 'websave(url)', as it should also contain 'filename' parameter saves content from the web service specified by 'filename'.
websave(filename,url)
Please refer to the documentation page: https://www.mathworks.com/help/releases/R2021a/matlab/ref/websave.html
Hope this helps
