高效和可靠的代码计算稀疏矩阵的不完全Cholesky因子作为预条件的共轭梯度算法。此代码实现了两个最近开发的改进的不完全因式分解算法。标准的不完全Cholesky分解的有效实施也包括在内。
Efficient and reliable code to compute incomplete Cholesky factors of sparse matrices for use as preconditioners in a conjugate gradient algorithm is described. This code implements two recently developed, improved incomplete factorization algorithms. An efficient implementation of the standard incomplete Cholesky factorization is also included.
