如果G的边集E(G)中有个子集M，满足M中的任何两条边 都不邻接，则M就是图G的一个匹配。包含边数最多的匹配 称为最大匹配，最大匹配所包含的边数称为最大匹配数。当 G是二分图时，问题就比较特殊了，这就是我们要解决 的问题——最大二分匹配。(If there is a subset M in the edge set E (G) of G, if any two edges in M are not adjacent, then M is a match of graph G. The match with the largest number of edges is called the maximum matching, and the number of edges contained in the maximum matching is called the maximum matching number. When G is a two point graph, the problem is very special. This is the problem we want to solve -- the biggest two points matching.)

SVPWM是近年发展的一种比较新颖的控制方法，是由三相功率逆变器的六个功率开关元件组成的特定开关模式产生的脉宽调制波，能够使输出电流波形尽可能接近于理想的正弦波形。空间电压矢量PWM与传统的正弦PWM不同，它是从三相输出电压的整体效果出发，着眼于如何使电机获得理想圆形磁链轨迹。SVPWM技术与SPWM相比较，绕组电流波形的谐波成分小，使得电机转矩脉动降低，旋转磁场更逼近圆形，而且使直流母线电压的利用率有了很大提高，且更易于实现数字化。(SVPWM is a novel control method developed in recent years. It is a pulse width modulation wave generated by a specific switching mode consisting of six power switching elements of three-phase power inverters, which can make the output current waveform as close as possible to the ideal sinusoidal waveform. Space voltage vector PWM is different from traditional sinusoidal PWM. It is based on the overall effect of three-phase output voltage, focusing on how to obtain the ideal circular flux trajectory of the motor. Compared with SPWM, the harmonic component of winding current waveform is smaller, which reduces the torque ripple of motor, makes the rotating magnetic field more close to the circle, and improves the utilization ratio of DC bus voltage greatly, and makes it easier to realize digitization.)

说明：  直接法求双谱，间接法求双谱，还有基于AR模型法求双谱。程序里面还提供了一种很方便的求对角线谱的方法，大家可以借鉴。总之，你下载了，绝对不后悔的。(Direct method bispectrum, bispectrum Indirect Method, as well as AR Model Method based on dual spectrum. Program which also provides a convenient way to find the diagonal spectrum, we can learn from. In short, you download, and definitely do not regret it.)

说明：  matlab的入门，金典书籍，值得一看。对于新手或刚入门的有很多帮助(matlab entry, Jindian books, worth a visit. For novice or just a lot of help getting started)
