RCWA

this is a code to use for speech recognition, it has another code instead of this code, call me for more detail

图像阈值分割程序，里面有好几个。运行ostu.m(Image threshold segmentation)

ERA模态参数提取方法，根据特征参数提取(MOdal ERA method)

This module will simulate any PV module with different weather conditions as an input. and is also connected to an simplified Maximum Power Point Tracker system to recognize the Working volrage of the cell (module)

详细的空时分组码程序，包括2发4收和4发4收，是初学者很好的学习材料。(Detailed space-time block coding procedures, including admission and 2 fat 4 fat, 4 received 4 is a very good learning materials for beginners.)

本程序模拟了火星、金星、水星等行星相对地球的运动轨迹，对于研究行星运动规律极有帮助。(This procedure simulated Mars, Venus, Mercury and other planets relative to Earth' s trajectory for the study of the law of planetary motion very helpful.)

说明：  最优化方法中的非线性最小二乘法,用于学习最优化方法和解决实际问题(The nonlinear least square method of optimization method is used to learn optimization method and solve practical problems)

A matlab function that calculates the inverse short term Fourier transform with adjustable parameters.

说明：  MATLAB仿真永磁同步电机直接转矩控制，传统滞环+开关表控制，仿真效果很好(The direct torque control of permanent magnet synchronous motor is simulated by MATLAB, and the traditional hysteresis plus switching table control has a good simulation effect.)
