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)

本代码为牛顿-SOR迭代法求解非线性方程组。其调用格式为[r,m]=mulNewtonSOR(F,x0,w,h,eps) 其中F:方程组，x0：方程组初始解，w：SOR迭代因子，h：数值积分常数，eps：根的精度，m：迭代步数。(The code for the Newton-SOR iteration method for solving nonlinear equations. Its call format [r, m] = mulNewtonSOR (F, x0, w, h, eps) where F: equations, x0: the initial solution of equations, w: SOR iterative factor, h: numerical integration constant, eps: the root of the accuracy, m: the number of iterative steps.)

我学习信号系统时原创的用matlab实现的谐波提取 ，两种方案，先分频再提基波，或者利用带通滤波器(I study the signal system to achieve an original harmonic extraction using matlab, the two programs, the first frequency and then Ti Jibo, or the use of band-pass filter )
