混沌动力学的平面模型，和对动力学的模型研究以其用户的输入(chaoic reserch ，the model ,and teh input model .)

Matlab教程第六章案例，时间序列分析与计量(Matlab Guide Chapter cases, time series analysis and measurement)

PSO-bp-MATLAB 5435654yhtr

准确混合噪声的成分,使AR模型的使用范围更为广泛。(Accurate mixing noise ingredients to make use of a wider range of AR model.)

利用matlab进行时域分析，本实验首录了三个音频。并编写程序求其特征值。特征值有平均值，整流平均值方差，标准差，方差，峭度，均方根，波形因子，峭度因子，峰值因子，脉冲因子，裕度因子。还有就是对音频进行自相关分析得出其波形图。(Use matlab time-domain analysis, the first experiment recorded three audio. Programming and seeking the eigenvalues. Characteristic values are averaged rectified mean variance, standard deviation, variance, kurtosis, RMS, crest factor, kurtosis factor, crest factor, pulse factor, margin factor. There is an audio self-correlation analysis of its waveform.)

用matlab 编写的英文字母识别的程序，附带样本和测试库，可以运行(alphabet recognition high performance)

RGB frame conversion

matlab中图像展开说明，适用于matlab中，很好的程序(matlab in image deployment instructions for matlab in a very good program)

利用matlab对声音信号进行消噪处理，最后进行总能量分析。(Use of matlab for processing sound signals to eliminate noise, and finally the total energy analysis.)

there are 5 files. the first two codes are written in Matlab as m-files in control system design to show step responses. in contrast, the final three codes are written in verilog ( Quartus II) used in Altera one of them for BCD adder and the other for four to two bits encoder circuit.
