中文摘要
我们实现了数值不稳定问题的高精度数值计算。该方法由多精度算法、正则化方案和基于再现核理论的高精度离散化规则组成。我们还举例说明了数值解在稳定格式下由于舍入误差积累而发散的情况。这意味着数值格式的理论稳定性并不等同于数值解的可靠性。
英文摘要
We have realized a high-accurate numerical computations for numerically unstable problems which arize in inverse or ill-posed problems. Our method consists of multiple-precision arithmetic, regularization scheme, and high-accurate discretization rules based on the theory of reproducing kernels. We also make examples where numerical solutions diverge under stable schemes due to accumulation of rounding errors. This means that theoretical stability of numerical schemes does not equivalent to the reliability of numerical solutions.
