Designs a linear phase FIR lowpass filter such that it: - minimizes maximum stopband attenuation - has a constraint on the maximum passband ripple This is a convex problem (when sampled it can be represented as an LP). minimize max |H(w)| for w in the stopband s.t. 1/delta <= |H(w)| <= delta for w in the passband ( where H is the frequency response function and variable is h (the filter impulse response). delta is allowed passband ripple. )

语音信号的盲源分离算法，其中包含了例子和算法(Blind source separation of speech signals, which contains examples and algorithms)

一般周期调制信号下的模拟ppm信号matlab仿真(general cycle modulation signal simulation ppm Matlab Signal Simulation)

Record your voice for 5 seconds Play back the recording Store data in double-precision array Plot the waveform Calculate over all the frames in the sample LPF the speech at 900 Hz to remove upper freq. (since Pitch info. will be below 900 Hz) Perform Centre Clipping and find the Clipping Level (CL) Choose the appropriate clipping level Perform Center clipping Compute the autocorrelation calcute pitch Calculate the avg. pitch estimate for the whole sample X.

Nothing to do, we need to learn how to trick something on the webs

s1.m: 低频波检测。能从高频信号中检测出低频信号。并将信号输出以70倍因子downsample. s2.m: 将downsampling滤波器输出信号，用单级速率和多相upsampling。 s3.m: 自动识别车牌位置。此程序能从一张图片当中，自动识别出车牌的位置。 s4.m: 用Hough变换识别出一张带有水池的图片的水池分界线。 s5.m: 用原始的静态多副图片（例如：恐龙图片）构造出三维旋转立体图片。(signal processing)

用simulink和s函数实现模糊比例参数自调整的代码(Simulink s function is used and the ratio of parameters of fuzzy self-adjusting code)

矩阵是数学中一个十分重要的概念，其应用能够十分广泛，Matlab中最基本最重要的功能就是进行矩阵运算，其所有数值功能都已矩阵为基本单元来实现，掌握Matlab中的矩阵运算是十分重要的(Matrix and its operation)
