MATLAB code for FIR filter design

可以实现FFT变化的时域图分析，可以清楚的知晓信号随时间的规律变化(Changes can achieve FFT time domain analysis, the signal can be clearly aware of the law change with time)

说明：  田纳西伊斯曼仿真数据，包括训练集和测试集(The Tennessee Eastman simulation data)

一杯沸水冷却，圆柱体模型，底面半径0.05m，高0.1m，周围温度20度，初始水温100度 方程是四维输运方程（常数a^2=k/(c*p)，k是热传导系数0.6006焦/（米*秒*度）） 初始条件：t=0时水等于100度 边界条件：1.上下壁都是自由冷却，第三类边界条件，周围温度保持在20度（H=k/h,h取1） 2.杯壁绝热，第二类边界条件 (cup of boiling water cooling cylinder model, the bottom radius of 0.05m, 0.1m high. temperature around 20 degrees, initial temperature of 100 degrees equation is four-dimensional equations (a constant ^ 2 = k/(c* p), k is the thermal conductivity coefficient of 0.6006 Coke/(m** seconds degrees)) initial conditions : t = 0 to 100 degree water boundary conditions : 1. upper and lower walls are free cooling, the third boundary conditions, maintain the temperature around 20 degrees (H = k/h, h for 1) 2. Beibi insulation, the second boundary condition)

用迭代法在MATLAB中实现（赫姆霍兹）Helmholtz方程组的求解(Solving Helmholtz equation set by iterative method in MATLAB)

matlab is good prgm for simulations and coding.do try this one

三次样条曲线函数 提取数据的样条函数 仅供参考 (spline function using spline interpolation to strike a group of data points in the points in the derivative (only provide functions))

说明：  APIT定位算法的matlab程序，APIT是一种经典的无线传感器网络定位算法。(APIT localization algorithm matlab program, APIT is a classic location algorithm for wireless sensor networks.)

学习matlab中的simulink的ppt，现在本人见过的最好的ppt。希望学习matlab中simulink的同志有所帮助(study of Matlab Simulink ppt, I would now seen the best ppt. China hopes to learn Matlab Simulink help comrades)

文件是编辑好的m文件，在matlab环境下，放在根目录下可以直接调用，有稳定性的判据，和校正环节的整定等等。(functions)
