Kuinka laskea Eigenvalue
Mikä on Eigenvalue?
An eigenvalue λ satisfies Av = λv for some non-zero eigenvector v. Eigenvalues reveal the characteristic stretching/compressing directions of a linear transformation.
Vaiheittainen opas
- 1Solve det(A − λI) = 0 (characteristic equation)
- 2For 2×2: λ² − trace(A)λ + det(A) = 0
- 3Find eigenvectors by solving (A − λI)v = 0
