Code For Permanent magnet synchronous generator model modelled with simulink matlab

这是一本通过MATLAB 环境下对数字信号进行处理的英文书籍。内容包括离散时间信号，离散傅里叶变换 时频分析等。是我很喜欢的一本书(This is a book by using MATLAB programming language for digital signal processing in English.and it includes Time-Frequency Analysis)

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)

介绍了MATLAB工具中的数学工具，是你用MABLAB开发时必不可少的参考书籍啊。(MATLAB tools introduced in the mathematical tools, is when you develop MABLAB indispensable reference books ah.)

说明：  标准label propagation的一个实现版本，实现为函数，可以直接调用即可。(As a standard implementation of label propagation algorihtm, you could integrate into your work freely.)
