递归法求解整数划分。 整数划分，是指把一个正整数n写成如下形式： n=m1+m2+…+mi （其中mi为正整数，并且1 <= mi <= n），则{m1,m2,...,mi}为n的一个划分。 如果{m1,m2,...,mi}中的最大值不超过m，即max(m1,m2,...,mi)<=m，则称它属于n的一个m划分。这里我们记n的m划分的个数为f(n,m) (Recursive method integer division. Integer division, refers to a positive integer n written as follows: n = m1+m2+ ...+mi (where mi is a positive integer, and 1 < = mi < = n), then {m1, m2, ..., mi} is a division of n. If {m1, m2, ..., mi} does not exceed the maximum value of m, i.e., max (m1, m2, ..., mi) < = m, m n is said that it belongs to a division. Where m is the number of division n our mind is f (n, m) )

matlab学习书籍，很有用的，大家可以根据这个自学！(matlab learning books, very useful, we can according to the self-study!)

说明：  使用simulink搭建的PMSM矢量控制，文件中附带详细的实验讲解和模型讲解，非常适合初学者(PMSM vector control built by simulink, detailed experiment explanation and model explanation are attached to the file, which is very suitable for beginners)

CRC循环冗余校验是数字数据通信中最常用的差错控制编码方法之一。在多种通信协议的帧结构中有一个 16位或32位的FCS(FrameCheekSequenee),就是利用CRC编码保证数据帧的无误传输。本文阐述7CRC循环 冗余校验码基本原理,根据实际系统需要,建立了并行处理算法的数学模型,并且在F尸GA芯片中实现了该并行算法。 (the resource of matlab)
