摘　　要：针对在进行64位里德所罗门码纠错算法设计的过程中,计算矩阵过于庞大,极其繁琐,人工计算无法实现的问题。该文提出一种应用于纠3个错误的(63,57)RS(里德所罗门码)生成多项式后矩阵计算的Matlab软件程序实现方法,该方法是通过应用一般行列式计算的原理,在Matlab中以逐行计算的方式实现。试验结果证明,通过该方法得到的数据准确,避免了人工计算所带来的误差,程序运行速度快使算法设计时间大幅缩短,效率明显提高。This paper proposed a programmer of Matlab applied to 64-bit error-correction RS coding to solve the problems of huge matrix and manual errors in the process of arithmetic design, which was used to calculate the matrix of the generator polynomial of （63,57）RS and correct three errors. The method used Matlab coding to operate the line-by-line calculation according to the principle of determinant calculation. The experimentation result shows that the method which educed correct results can avoid manual errors and improve the efficiency of the design as the computer can run very fast.
