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