数值计算方法中的一个上机实验，雅克比迭代法，一份很详细的实验报告，包括源码-Numerical methods in an experiment on the computer, Jacobi iterative method, a very detailed lab report, including source code

求解椭圆方程的jacobi迭代,其中边界采用的是重叠一层网格点的边界替换。-Jacobi iterative solving elliptic equations, Which uses a boundary layer of overlapping grid point boundary replacement.
