主要模拟的是信号光在增益光纤中放大的过程(Main simulation signal light is amplified in the gain fiber in the process)

利用罚函数法求解下列问题：求f=x1^2+4*x2^2的最小值，其中要满足：x1-x2-1≤0 -x1-x2+1≤0 x2-1≤0 (Using penalty function method to solve the following questions: o f = x1 ^ 2+ 4* x2 ^ 2 minimum value, which will meet: x1 x2-1-0 or -x1 x2+ 1 or 0- X2-1 or 0 )

MATLAB tftb工具箱,上面有安装文件和安装说明(tftb MATLAB toolbox, where the installation file and install)

this is a code for gui and it contains the matlab language codes and its really working codes.i think it will work for the people who are looking for it

program to find the classification using matlab programming

很多经典函数的图形演示，让你更直观的了解一些经典函数的模样。其中的函数可以直接用来参考应用(Many of the classic function of graphical presentation, make you more intuitive understanding of some of the classic function looks like. One of the functions can be directly used to refer to the application)

OFDM is a frequency-division multiplexing (FDM) scheme used as a digital multi-carrier modulation method. A large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels.

QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

原始snake matlab 源碼，簡單版( seg = localized_seg(I,init_mask,max_its,rad,alpha,method) Inputs: I 2D image init_mask Initialization (1 = foreground, 0 = bg) max_its Number of iterations to run segmentation for rad (optional) Localization Radius (in pixels) smaller = more local, bigger = more global alpha (optional) Weight of smoothing term higer = smoother method (optional) selects localized energy 1 = Chan-Vese Energy 2 = Yezzi Energy (usually works better))

这个是利用MATLAB实现的KNN算法的实现(This is achieved using MATLAB algorithm to achieve KNN)
