去斜率（strech）参考信号与回波信号混频后得到中频输出信号S(t)=Aexp(j*2*pi*f0*t+phase) 其中f0与回波延时的关系为： f0=k*delay_t K为线性调频斜率，delay_t为回波延时 将s(t)采样，FFT变换即可得到目标距离与频谱的关系。 Strech 信号测距 输入混频后的中频信号（图一），经采样及FFT变换得到频谱（图二） 再根据频谱与距离的关系式R=Tcf/2B显示出距离(图三) (Go slope (strech) obtained after the reference signal and the echo signal mixer IF output signal S (t) = Aexp (j* 2* pi* f0* t+phase) f0 and echo delay relationship: f0 = k* delay_t K chirp slope, delay_t the echo delay sampling s (t), the FFT transform to the target distance spectrum of relations. Strech signal ranging input mixer IF signal (Figure 1), sampling and FFT transform spectrum (Figure 2) according the the spectrum distance relationship R = Tcf/2B shows the distance (Figure 3))

一种光滤波器仿真设计.具有一定局限性.通过先行缔造滤波器频谱图,进行设计仿真(Simulation design of an optical filter has certain limitations. Plan first to create a filter spectrum, to simulate the design)

音乐合成 内容：1) 自己朗诵一段文字，并录制成.wav 文件； 2) 利用 matlab，给这段录音添加背景音乐； 代码都嫁了注释(use matlab, add background music to the recording which you read a text )

用遗传算法求解函数最优问题，注释详细，过程详细，值得参考和学习，稍微修改能用于解答其他问题！(Function using genetic algorithm optimization problem, detailed notes, the process in detail, it is worth reference and learning, a slight modification can be used to answer other questions!)
