摘　　要：就曲线的长度积分分析了Matlab中三个一维积分函数程序的共性问题,当被积函数可积,函数值在积分区间的端点处无界时,可能会使程序出错,积分失败。分析了程序运行失败的原因,并提出解决方法。提高了Matlab中积分函数的可靠性,增加了用户程序的稳定性。The common problems of three one-dimensional integral function programs in Matlab are analyzed for the length integral of curves.When the integrand is integrable and the value of the function is unbounded at the end of the integral interval,the program may make mistakes and the integral may fail.The reasons for the failure of the program are analyzed,and the solutions are put forward.It improves the reliability of integral function in Matlab and increases the stability of user program.
