研究生数值分析课程的matlab的算法的讲义，适合科研人员使用。(Numberal Analysis based on matlab.)

this is simple sample of SOM & modified SOM (mSOM) neural network. main file : SOM.m

Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )

多元逐步回归算法,在matlab软件中的运用,简单实用 (multiple stepwise regression algorithm in Matlab software on the use of simple and practical)

（1） 分别采集一段浊音和清音语音信号（是你自己说的），采样率为8KHZ，量化精度为16比特线性码； （2） 分析帧长取为30ms（或10ms～50ms）； （3） 根据语音信号倒谱分析和LPC谱分析的编程流程图（图2.1、图2.2）编制浊音语音信号谱分析的matlab程序，上机调试给出相应波形，并根据图形，观察共振峰情况； （4） 将语音信号换为清音语音，运行程序，与浊音语音的运行结果进行比较，并得出结论。 （5） 在LPC谱分析中，改变阶数p （p分别等于4、8、12、40）时，观察对谱包络的影响，并与信号谱（DFT谱）进行比较。 ( voice signal processing)
