说明：  最小化l1范数的Matlab代码。求解模型为： min lambda*|x|_1+||A*x-y||_2。其中，|x|_1表示x的1-范数，||*||_2表示2-范数。该模型在稀疏成分分析、压缩传感器等领域有广泛的用途。( l1-Regularized Least Squares Problem Solver l1_ls solves problems of the following form: minimize ||A*x-y||^2+ lambda*sum|x_i|, where A and y are problem data and x is variable (described below). )

IIR滤波器的经典分析与比较，包括切比雪夫I型，II型、椭圆等！转换方式，冲击法，双线性（带通）(The classic IIR filter analysis and comparison, including chebyshev type I, II, elliptical, etc.! The switch pattern, impact method, double linear （bandpass filer）)

牛顿-拉夫逊法在数学上是求解非线性代数方程组的有效方法，其要点是把非线性方程求解过程变成反复地对相应的线性方程进行求解的过程。(Newton- Raphson method in mathematics is an effective method for solving nonlinear algebraic equations, the point is that the non-linear equation solving process into the process repeated for the corresponding linear equation solving.)

说明：  modelling of two cstrs in series. chemical

UWB，超宽带信号分析必用的子函数，第13部分！(UWB, ultra-wideband signal analysis will be used for Functions, Part 13!)

计算X光机拍出的一幅图像有多少个坏点，就是说可以计算出有多少个像素不正常的点，经过反复验证了的。(How many dead pixels calculated X-ray machine to shoot an image, that can calculate the number of pixels in the normal point, after repeated verified.)

该文件夹中包含了BPSK调制与解调中常使用的子程序(This folder contains a BPSK modulation and demodulation often use subroutine)

有监督自组织映射-偏最小二乘算法(A supervised self-organising map–partial least squares algorithm),可以用语多变量数据的回归分析(supervised self-organizing map- Partial Least Squares (A supervised self-org anising map- partial least squares algorithm) , terms of the multi- variable regression analysis of data)

fir滤波器，7、8、13、14，对信号进行alpha、betagamma滤波，调用方法 Hd = fir_alpha 滤波后信号 = filter(Hd,原信号) 得到的信号是时域信号，plot直接显示(Fir filter, 7, 8, 13, 14, alpha filter for signal method is called Hd = fir_alpha After filtering signal = filter (Hd, the original signal) Signal is time domain signals, the plot showed directly)
