Eigenvalues and maybe eigenvectors of symmetric 3x3 matrix. Computes the eigenvalues and, optionally, the eigenvectors of a symmetric 3x3 input matrix A, i.e. computing diagonal matrix W as the eigenvalues W, and orthogonal matrix of eigenvectors Z such that ![]()
If Z is passed as NOTE: the contents of A are NOT destroyed. The eigenvalues W are provided in ascending order. |
