Good evening,
are there any MATLAB commands to clear a ThingSpeak channel?
I found this link but I can't use the commands:

Try this:
ChannelID = YOUR_CHANNEL_NUMBER;
UserAPIKey = 'YOUR_USER_API_KEY'; % This is available from https://thingspeak.com/account/profile
url = sprintf('https://api.thingspeak.com/channels/%s/feeds.json?api_key=%s',num2str(ChannelID),UserAPIKey)
response = webwrite(url, weboptions('RequestMethod','delete'))

Thank you Vinod for the support, the Script that you send me work perfectly.
Now I can clear my ThingSpeak channels directly from MATLAB.
Thanks
Mirko

You can use the script that Vinod posted in MATLAB analysis in ThingSpeak to programatically delete a channel.

Ok I still don't see any script, how do I use a script that I don't have? Thank you

Try this one and then modify it to have the channel values you need.
