D.3.2.18 eigenvals
Procedure from librarylinalg.lib (see linalg_lib).
- Usage:
- eigenvals(M); matrix M
- Assume:
- eigenvalues of M in basefield
- Return:
list l; ideal l[1]; number l[1][i]; i-th eigenvalue of M intvec l[2]; int l[2][i]; multiplicity of i-th eigenvalue of M
LIB "linalg.lib"; ring R=0,x,dp; matrix M[3][3]=3,2,1,0,2,1,0,0,3; print(M); ==> 3,2,1, ==> 0,2,1, ==> 0,0,3 eigenvals(M); ==> [1]: ==> _[1]=2 ==> _[2]=3 ==> [2]: ==> 1,2 |
