quantization wavelet to generate step signal

采用神经网络实现手写识别的一种方法，建立Bp神经网络，采用快速训练方法，可快速完成一类相关手写字体的模式识别，识别率较高，当字体变化较大识别率降低时，可重新训练具有较强的适应性。实验证实本方法较好实现了手写字符识别，但也存在识别速度较慢，有时训练不收敛等缺点(Handwriting recognition using neural network is a way to establish Bp neural network, using fast training methods, and can be related to the completion of a class of handwriting pattern recognition, recognition rate higher recognition rate when the font changed greatly reduced, they can re- Training has strong adaptability. Experiments confirmed that this method achieved a better handwritten character recognition, but there are also identified slow, and sometimes non-convergence of the training deficiencies)

说明：  数据通信中误码检测机制的研究，使用MATLAB对二维奇偶校验码进行测试(Studies of Error Detection Techniques in Data Communications，two-dimensional parity check is simulated through MATLAB)

基于matlab的工具箱，应用模糊控制系统方法设计实现PID控制。(Based on Matlab toolbox, the application of fuzzy control system design method achieves the PID control.)

this is a simulink program tat simulates a an iduction motor being controlled via a converter and has a load that consists of an elevor load and a counterweight
