重要的模糊支持向量机训练算法，对研究模糊支持向量机很有帮助(Important fuzzy support vector machine training algorithm, the study of fuzzy support vector machine is very helpfu)

这是Matlab中全书最重要以及常用的源码，相当于一个简易的字典(This is the most important book of Matlab, as well as commonly used source, which is equivalent to a simple dictionary)

: 针对实际振动位移难以获取的问题, 利用振动位移与加速度信号之间的关系, 先对采样后的加速度信 号采用时域数值积分,得到含有趋势项的速度信号及位移信号,再采用拟合多项式极值的方法, 消除积分过程 中产生的趋势项,从而得到更为精确的速度和位移信号. 算例表明, 利用拟合多项式极值消除趋势项的方法, 得到的位移时程曲线拟合精度高(: In pract ical engineering , the collection of displacement data is mo re dif ficult than that of the acceleratio n data in the time-domain .Displacement sig nals w as g ot f rom acceleration s ignals using aumerical integrat ion , wi th the t rend o f erro r.
