Nettet1. jan. 2024 · The matrix you pass to lstsq should have columns of the form f (x) where f runs through the terms you allow in the model. So if it's a general linear model, you'll have x**0 and x**1. With zero intercept forced, it's just x**1. In general these don't have to be powers of x, either. Output for degrees = [1], model y = bx.
