SEGMENTATION CODE FOR LUNG CANCDDER

说明：  此仿真实现了三电平的有源逆变，且功率因数可调(The simulation of the three-level inverter, and active power factor can be adjusted )

wireless sensor network localization estimation using distance vector one hop

利用该代码，可以计算各子信道的功率谱。看出哪些信道是最强的 (caiculating the PDP of the subchannel)

%solve u_xx + u_yy = f(x,y) % over the region D = [x0,xf,y0,yf] = {(x,y) |x0 <= x <= xf, y0 <= y <= yf} % with the boundary Conditions: % u(x0,y) = bx0(y), u(xf,y) = bxf(y) % u(x,y0) = by0(x), u(x,yf) = byf(x) % Mx = # of subintervals along x axis % My = # of subintervals along y axis % tol : error tolerance % MaxIter: the maximum # of iterations

说明：  径向基函数神经网络的优点：逼近能力，分类能力和学习速度等方面都优于BP神经网络，结构简单、训练简洁、学习收敛速度快、能够逼近任意非线性函数，克服局部极小值问题。原因在于其参数初始化具有一定的方法，并非随机初始化。代码为RBF的matlab程序，可以使用但是需要自己配置数据。(Radial Basis Function Neural Network (RBF-NN) has the advantages of better approximation ability, classification ability and learning speed than BP Neural Network (BP Neural Network). It has simple structure, simple training, fast learning convergence, and can approximate any non-linear function to overcome the local minimum problem. The reason is that its parameter initialization has a certain method, not random initialization.)
