Matlab code to reconstruct using back projection

matlab 主成分分析，内含数据和程序源码。很好的数学建模资料(Principal component analysis )

1.实验目的：绘制分形图案并分析其特点。  2.实验内容：绘制Koch曲线、Sierpinski三角形和树木花草图形，观察这些图形的局部和原来分形图形的关系。  3.实验思路：利用函数反复调用自己来模拟分形构造时的迭代过程，当迭代指标n为0时运行作图操作，否则继续迭代(1. Purpose: Draw fractal patterns and analyze their characteristics. 2. Experiment: Draw Koch curve, Sierpinski triangle graphic flowers and trees, observe the relationship between the local and original graphics fractal graphics. 3. Experiment idea: using the function calls itself repeatedly to simulate the iterative process when the fractal structure, when the iteration index n is plotted 0:00 run, otherwise continue iterating)

说明：  基于matlab的GUI界面设计的成绩管理系统，可以直接用！(Based on the matlab GUI interface design of the performance management system )

模式识别的一部分，用于确定二值边界的，不错的算法额(Part of a pattern recognition algorithm for binary boundary determined )

信号方位估计esprit算法 是用多项式求解的方法来寻找DOA(esprit arithmetic of DOA.the polynomial method to find DOA (Direction of Arrival))

随机采样文件1，在MATLAB上进行仿真的(random sample)
