%description
Implementation of a conjugate-gradient type method for solving sparse
linear equations: solve Ax = b or (A - sI)x = b. The matrix A - sI must
be symmetric and nonsingular, but it may be definite or indefinite. The
scalar s is a shifting parameter -- it may be any number. The method is
based on Lanczos tridiagonalization. You may provide a preconditioner,
but it must be positive definite.
%description -l pl.UTF-8
Implementacja gradientowej metody rozwiązywania rzadkich układów równań
liniowych, postaci Ax = b albo (A - sI)x = b. Macierz A - sI musi być
symetryczna i nieosobliwa, ale nie musi być określona. Skalar s może być
dowolną liczbą. Metoda jest oparta na trójdiagonalizacji Lanczosa. Można
jej dostarczyć dodatnio określony preconditioner.
