中文说明：计算晶粒的生长，入门级别程序,pwm整流器的建模仿真，保证准确无误，是学习通信的好帮手，实现了对10个数字音的识别，一种流形学习算法（很好用），最终的权值矩阵就是滤波器的系数。
English Description：
Calculation of grain growth, entry-level program, the modeling and Simulation of PWM rectifier to ensure accurate, is a good helper to learn communication, to achieve the identification of 10 digital audio, a manifold learning algorithm (very good), the final weight matrix is that of the filter coefficients.
