DFBREC_L Directional Filterbank Reconstruction using Ladder Structure x = dfbrec_l(y, fname) Input: y: subband images in a cell vector of length 2^n f: filter in the ladder network structure, can be a string naming a standard filter (see LDFILTER)

用matlab实验水平集，运用到灰度图像上面可以得到的很好的分割效果，下载后可以直接运行得到结果(Matlab experiment level set, apply to the gray image, it can get very good segmentation effect can be run directly after download the result)

凸优化算法,实现凸优化的求解，应用在最优化的设计和参数估计中(convex program)

PDE for Matlab, I like it(PDE and ODE matlab book)

空间风场模拟程序，采用谐波平衡法模拟大气边界层(code for simulation of wind field of boundary layer.)

张量的模式展开是一个基本的技术，已有各种代码展开结果不尽相同，本代码是根据张量研究领域权威文献“Tensor Deco们positions and Applications”中的公式编写，并经过多次实例验证，与理论描述相符。文件包括两个m文件，一个是按模n展开，而另一个是逆变换，即按模n叠合。(unfolding of the tensor mode is a basic technology, there are a variety of code to make different result. However this code is written by referring to the authority of the tensor field of research literature Tensor Deco their positions and Applications and after several instances verification, is consistent with the theoretical description. The documents include two m-files, one is unfold.m, and the other is the inverse transformation, that is refold.m.)
