下面是用 Fortran 90 语言编制、在Fortran PowerStation 4.0 集成开发环境下运行的ICCG法计算机程序，该程序也同样适合于在Visual Fortran 6.5环境下运行,不需要改动。其算法参见5.2.2、5.2.3。-The following is compiled with the Fortran 90 language, the Fortran PowerStation 4.0 integrated development environment running under the ICCG method computer program, the program is also suitable for use in Visual Fortran 6.5 environment, and does not require changes. See 5.2.2,5.2.3 the algorithm.
