introduction for plotting graphs in matlab

这个程序是对系数矩阵进行乔列斯基分解，并对线性方程组求解的通用程序(This program is the coefficient matrix Qiaoliesiji decomposition, solving linear equations and general program)

matlab7.X程序开发以及matlab编程学习(matlab7.X program development and learning matlab programming)

代码是matlab编写，有例图，可直接运行（注意修改路径）。主要用来检测桥面、路面裂纹，有详细函数功能说明和算法思想，实现了路面规则条纹背景的频率估计，采用频域滤波可有效去除路面图像接近估计频率的噪声，保留目标裂纹，实现了初步的检测功能，但是功能还不完善，可作Demo供大家参考。有兴趣的朋友可以逐步完善、移植，有兴趣的朋友请与我联系。(Matlab code is written, there is case diagram, can be run directly (Note to modify the path). Mainly used to detect bridge, road cracks, a detailed description and algorithms Function thinking to achieve a frequency of road rules striped background estimation, using frequency domain filtering can effectively remove the image close to estimate the frequency of road noise, keep cracking goal to achieve a preliminary detection function, but the function is not perfect, can be used for Demo for your reference. Interested friends can gradually improve, transplant, friends who are interested, please contact me.)

面阵中二维角度估计 UNITARY -ESPRIT算法MATLAB程序(Two-dimensional planar array angle estimation UNITARY-ESPRIT algorithm based on MATLAB program)

利用重复轨道卫星数据计算轨道之间的基线（即空间距离）实现数据获取时间内任意位置的基线长度，并存入文件中。(Repeat orbit satellites using data between tracks baseline (i.e. spatial distance) for data acquisition time of the baseline length anywhere within and into a file.)

这是VAD有关代码。也就是说为了在音声中找到activity voice 用GAET方法来决定阈值，然后判别了无音区间。(voice activity detection)
