LINPACK Copyright Information

We have translated some of the FORTRAN procedures of LINPACK dongarraetal@79 into C. We have used all of the basic linear algebra subroutines (BLAS) as well as subroutines to do the $QR$ factorization of the matrix $\mathbf{X}$ of the linear system

$$\vec{y} = \mathbf{X} \cdot \vec{b}$$

These include the subroutines SQRST, STRSL, SPODI, SQRSL and SQRDC. Not all of the optimizations have been translated. These subroutines are used quite extensively in the analysis modules. The original FORTRAN subroutines are Copyright (C) 1979 by the Society for Industrial and Applied Mathematics.
