薛定宇教授编写的MATLAB控制分析工具包Ctrllab 如题，该工具包解压后，通过MATLAB修改路径后，直接运行ctrllab，即出现可视化界面，可进行时域、频域、复域的各种分析，比如bode图，奈氏图等等，超级好！对控制专业的同志来说，用处极大！(Prepared by Professor Xue Dingyu MATLAB control analysis tools package Ctrllab such as title, package and extract the tool MATLAB modify the path directly run ctrllab, that appear visualization interface, can be time-domain, frequency domain, the complex domain of all kinds of analysis, such as bode Figure Nyquist plot, and so on, super good! Comrades who control professional, extremely useful!)

DistMesh giving a singular FEM matrix?(Hi Anyone here with some experience of using DistMesh in finite element code? I m solving the scalar Helmoltz equation in an annular region in 2D: rho_1 < rho < rho_2 where rho_1 is the radius of a Perfect Electric Conducting cylinder and rho_2 is where the mesh is truncated using an Absorbing Boundary condition. Now, I ve written code to mesh the region myself (by dividing the region into annular rings and picking a fixed number of points on each ring) and I ve written another program which uses DistMesh to mesh the region. I get a nice solution using my own meshing code but the FEM matrix becomes singular when I use DistMesh. This is the DistMesh Code I used: Circle with hole rABC=1.5 rCyl=0.5 fdstring=sprintf( ddiff(dcircle(p,0,0, f),dcircle(p,0,0, f)) ,rABC,rCyl) fd=inline(fdstring, p ) box=[-2,-2 2,2] [p,N]=distmesh2d(fd,@huniform,0.04,box,[]) I tried changing box and the 0.04 value (initial edge length). But every time, the matrix becomes sin)

prony算法做相关仿真，可自行更改pe，也可调整p。(Prony algorithm is used to do related simulation, and PE can be changed or P can be adjusted.)

这个环境最简单的是 gcc + glibc + linux-header + make 。另外还要看你的目标环境。(gcc+ glibc+ linux)

ISODATA算法实现，个人编写，结果正确，matlab 实现(ISODATA algorithm, personal writing, result is correct, matlab implementation)
