RangeError: Submatrix indices are out of range
Usage:
const pca = new PCA([vector]);
const result = pca.predict([vector], { nComponents: 2 });
...where vector is an array with 1,536 elements a la an Open AI embedding. E.g. const vector = [0.00728, -0.0181, 0.014, ....]
The goal is to reduce/project the 1,536-element vector into 2d space for graphing related vectors.
However, when I call pca.predict, it throws this error:

[snipped]
No, sorry, I moved on to a different method of doing this all together, I decided that vector space projection wasn't all that relevant to what I was trying to do so I didn't work out a work around, sorry!

Alright, thank you, Joshiah. For transparency, I ended up just using the OpenAI's embeddings instead. https://platform.openai.com/docs/guides/embeddings Maybe I'll revisit this later.
I'm confused - are you saying OpenAI's embeddings provides some sort of dimensional reduction built-in?
