WebHere is how I would do it, but solving by inspection is subjective anyway. Let A be the matrix of coefficients, then ( A ⋅ x) k = λ x k. Add the third and the second row. This gives x 2 + x 3 = λ ( x 2 + x 3), thus λ = 1 or x 2 + x 3 = 0. Since the trace of A equals 1, the sum of other two eigenvalues is 0. WebJul 11, 2024 · The Eigenvectors (principal components) determine the directions of the new feature space, and the eigenvalues determine their magnitude.
