一维灰度矩，用matlab进行编程，输入为一维灰度序列，输出为边缘值。不能直接处理图像！但有学习研究价值。(One-dimensional gray moment, using matlab programming for one-dimensional gray-scale input sequence, the output value for the edge. Can not directly deal with the image! But learning research value.)

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)

建立routh阵列表的函数，建立胡尔维茨的函数，是判定系统稳定性的很好工具。(routh array of links to establish the function of the establishment of the H-Polynomial function, System stability is convicted of a good tool.)
