输入字母和目标矢量产生程序，matlab编程(Enter the letters and the target vector generation process, matlab programming)

continous uniform random variable

QPSK仿真，误码率计算及其仿真结果的比较(QPSK )

说明：  内存dc，内存dc是用于双缓冲，以解决重绘闪烁的问题(Memory dc, memory dc for double buffering to resolve the issue of flickering redraw)

pwm没有做SVPWM，而仅仅是单极性PWM。PI参数调试的不是很好，可能调制波波形不太好(pwm did not do SVPWM, while the Unipolar the PWM. PI parameters debug not very good, may be modulated waveform is not very good)

model induction motor

生成纵横向四阶方程，计算特征根，传递函数等，给出波特图及尼科尔斯图。( SURVEY is set up to make calculations based on the 12 x 12 Fmodel and 12 x 7 Gmodel produced by FLIGHT, with the generic business jet model trimmed for flight at V = 102 m/s and h = 3,050 m. The flags are set to generate a fourth-order, body-axis, lateral-directional model the data set to calculate eigenvalues, eigenvectors, and the transfer function aileron to roll rate and to show the Bode plot, Nyquist plot, and Nichols chart for the transfer function.)

语音识别的MATLAB代码，包括用于测试的语音，实现了利用HMM(隐含马尔可夫)和DTW(动态规划)两种方法的实现。(ASR use HMM and DTW method include wave files use for test and training.)
