DEC/SOL: solution of dense systems of linear algebraic equations. [DEC and SOL subroutines in FORTRAN IV]
Technical Report
·
OSTI ID:7329469
This report describes four versions of a pair of subroutines for solving N x N systems of linear algebraic equations. In each case, the first routine, DEC, performs an LU decomposition of the matrix with partial pivoting, and the second, SOL, computes the solution vector by back-substitution. The first version is in Fortran IV, and is derived from routines DECOMP and SOLVE written by C. B. Moler. The second is a version for the CDC 7600 computer using STACKLIB. The third is a hand-coded (Compass) version for the 7600. The fourth is a vectorized version for the CDC STAR. Comparative tests on these routines are also described.
