eigenvalue and vectors of a symmetric 2x2 matrix
Syntax
lambda = eig2(M)lambda = eig2(a11,a12,a22)[lambda,v1,v2] = eig2(a11,a12,a22)[lambda,omega] = eig2(a11,a12,a22)Input
| M | array of symmetric 2x2 matrix |
| a11, a12, a22 | vectors of matrix elements |
Output
| lambda | eigen values (first column small one, second column large one) |
| v1 | list of eigen vectors to the smallest eigen value |
| v2 | list of eigen vectors to the largest eigen value |
| omega | angle of the largest eigen vector in [0,pi] |
