摘要 混合模型方程组间接迭代法可以省去建立混合模型方程组的繁杂过程,而直接根据观察值数据文件和系谱文件进行迭代求解,因而计算速度很快,编程方法也非常简单。本文用直观的事例详述了混合模型方程组的Gauss-Seidel间接解法,使该方法更容易被领会。 The indirect solution of mixed model equations don't need to set up miscellaneous mixed model equations but to iterate from data file and pedigree file directly,and it is very convenient and simple. We can program easily and it can run rapidly. The article show Gauss-Seidel indirect solution of mixed model equations with explicit example,which make the method be understood easily.
