matlab的gui工具实现计算器 包括加减乘除以及三角函数，反三角函数(matlab gui tools to implement the calculator, including addition, subtraction, and trigonometric functions, inverse trigonometric functions)

源代码集合，大家可以找找看有没有自己需要的，要分批实在太慢了，只好打包一块。(source code set, we can look to see whether they need to batches had been very slow, but a package.)

数字信号处理实验，噪声中正弦信号的经典发频谱分析(Digital signal processing experiments, classic sinusoidal signal noise spectrum analysis hair)

分别用C++，matlab以及Fortran语言实现bp算法(bp algorithm using C++, matlaband Fortran language)

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))
