ThingSpeak - is `downsample` included?

Hello,

I am trying to learn from the weather data example but I can't get it to work: Analyzing Weather Data from an Arduino-based weather station

I get this as an error:

'downsample' is used in Automatically Tune Filter to Track Maneuvering Targets.

Is downsample included with the ThingSpeak Visualization tool?

Thanks

No — downsample is not part of the ThingSpeak Visualization tool. It's a MATLAB function, and ThingSpeak supports MATLAB code, but it depends on what toolboxes are available in your license.

I hope I understood your question correctly—please feel free to correct me if I didn’t.

In particular the Mathworks downsample() function is part of the Signal Processing Toolbox
