D.3.2.17 hessenberg
Procedure from librarylinalg.lib (see linalg_lib).
- Usage:
- hessenberg(M); matrix M
- Assume:
- M constant square matrix
- Return:
- matrix H; Hessenberg form 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 print(hessenberg(M)); ==> 3,2,1, ==> 0,2,1, ==> 0,0,3 |
