15TMatrixTCramerInv
16
17Encapsulate templates of Cramer Inversion routines.
18
19The 4x4, 5x5 and 6x6 are adapted from routines written by
20Mark Fischler and Steven Haywood as part of the CLHEP package
21
22Although for sizes <= 6x6 the Cramer Inversion has a gain in speed
23compared to factorization schemes (like LU) , one pays a price in
24accuracy .
25
26For Example:
27~~~
28 H * H^-1 = U, where H is a 5x5 Hilbert matrix
29 U is a 5x5 Unity matrix
30
31 LU : |U_jk| < 10e-13 for j!=k
32 Cramer: |U_jk| < 10e-7 for j!=k
33~~~
34
35however Cramer algorithm is about 10 (!) times faster
