it would seem that this would be a commonly sought-after topic, however I cannot find straightforward libraries for this and it's taking too long, so please allow me the question:
Is there a good library for Arduino/ESP32 to run principal component analysis (PCA) on a 3D matrix? Any links etc welcome, EigenArduino is the 'only' library I could find but it's not exactly straight forward (no example code etc). I want to extract the first component of some data sized 3x3000.
Thanks
