WebJul 27, 2015 · 1 Answer. When you perform principal component analysis (PCA) on your 27 points in 3D, you first subtract the mean vector m and then obtain three eigenvectors e 1, e 2, e 3 of the covariance matrix. The first two eigenvectors (with two largest eigenvalues) span the plane that you want to find, so the geometric situation looks like that: a x + b ...
