这段程序是产生一个叠加信号，然后计算传递函数，进行相关分析(this is a program which generate a new signal,calculate transfer function and doing correlation analysis )

非常好的偏最小二乘分析的程序，包含了典型相关分析、主成分分析和多元线性回归。可以根据具体的需要更改代码变成非线性回归，建立多个自变量和多个因变量之间的关系应用很广。包含计算程序和画图表示结果的程序两个m文件(Very good partial least squares analysis of programs, including the canonical correlation analysis, principal component analysis and multiple linear regression. It can become a non-linear regression, depending on the need to change the code to establish relationships between multiple independent variables and multiple dependent variables very wide application. Program includes the calculation procedures and drawing showing the results of two m files)

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)

说明：  实际的数值是带有符号的，即可能是正数，也可能是负数，数值的正负之分如何实现？ 通过补码表示，且用一位符号位区别其正负即可。 而数值本身可以包括整数，也可以包括小数。那么，在计算机中是如何确定小数点的位置呢？ (The actual value is unsigned, which may be positive, it may be negative, positive and negative values divided how? By complement representation, and with a bit different from the positive and negative signs can be. The value itself can include an integer, it can also include decimals. Then, the computer is how to determine the decimal place?)
