How to read data from your thingspeak on Matlab Analysis

Hi Team

I am following the link to send email using ThingHTTP and Matlab Analysis, On Matlab Analysis do i change the channelID, URL and field name? Reason for this i see its a default example. How does now IFTT merge it with my thingspeak channel? In order to receive email notification about my channel from thingspeak. https://www.mathworks.com/help/thingspeak/use-ifttt-to-send-text-message-notification.html

I would start with thingSpeakRead function in MATLAB.

data = thingSpeakRead(12397,'Fields',[1,4],'NumPoints',3,'OutputFormat','TimeTable')

If you have a private ThingSpeak channel, you will also need to supply your Read API Key.

I personally think the documentation page Hans linked is more useful than the 2 lines of code this video shows.
