二维绘图—MATLAB(有关matlab绘图的各种基本知识，实用)(2 d graphics- MATLAB)

此程序描述OFDM系统中多径衰落信道的仿真和实现，包含信道转移矩阵的计算和变换等(This procedure describes the OFDM system simulation and implementation of multipath fading channels, including the calculation and conversion channel transfer matrix, etc.)

FIR 滤波器的低通，带通，高通实现，matlab(FIR using matlab)

1) 已知x=[1:15], y=[12 34 56 78 99 123 165 198 243 277 353 345 303 288 275], 用多项式进行拟合，给出拟合多项式，(所选拟合多项式阶数不同，拟合结果不同，请你选择适当的阶数进行拟合)，并绘出原始数据点、拟合曲线和95％置信区间（confidence bounds）的图形 . 2) 根据下面数学模型建立仿真模型，并在一个示波器中把它们的波形仿真出来。 (1) are known to x = [1:15], y = [12 34 56 78 99 123 165 198 243 277 353 345 303 288 275], with polynomial fitting, given the polynomial fitting, (the election order polynomial fitting different fitting results to differ, please select the appropriate order of fit), and draw original data points, fitting curve and 95 confidence interval (confidence bounds) graphics .2 ) In accordance with the following mathematical model for the establishment of simulation model, and in an oscilloscope waveform in their simulation out.)

说明：  matlab实现加汉明窗，矩形窗，并对它们进行傅里叶变换，并实现频谱的分析。(matlab realize Jia Hanming window, rectangular window, and they are subjected to Fourier transform, and to achieve the analysis of the frequency spectrum.)

基于fisher准则的线性分类器，每类7个样本(Criteria based on fisher linear classifier, each class of seven samples)

数据采集GUI与分析,可以读取与保存数据，用于串口控制(data collection and anlysis in GUI)

可以看到 变步长未必会需要更长的时间 因为它是一种自适应的方式 如果某阶段情况理想的话 就会用最大步长来做 那就会很快 (can see variable step may not need a longer period of time because it is an adaptive way if a certain phase of the the ideal would be the greatest step will be to do it quickly)
