I've heard of Matlab many moons ago, but never had the chance to use it myself. This "sandbox" page is used to test some simple Matlab / ThingSpeak code I have written which probably will not look pretty at all right now. But I'm confident that it'll improve over time.
If you interested in the code you can find it on GitHub where I've created a MatLab-Code directory within the GitHub project. The first file uploaded is named MinMaxVisu which generates a simple text output.
As a reference for myself how to code with Matlab I'll post some links on this page pointing to Matlab's documentation as well.
Simple text output using MinMaxVisu:
Maximum and minimum temperatures of past 24h
Maximum temperatures of past 24hs
Minimum temperatures of past 24hs
