Based on the Matlab script for DFT-S-OFDM with plot

一种改进的BP算法，基于动量梯度的，非常经典，实际可用(An improved BP algorithm based on the momentum gradient, very classic, the actual available)

fuzzy PD control of dynamic system

• Batch least squares for training a Takagi-Sugeno fuzzy system

用matlab编写的电磁学方面的函数和图像(Prepared by using matlab function aspects of electromagnetics and images)

电网络节点电压，节点关联矩阵的自动生成和计算(Voltage, electric network node automatically generated and calculation of the correlation matrix)

用c++语言，生成一个能让MATLAB自动加载的数据格式文件。该工具能够编译成为dll文件，随着其他文件一起动态执行和动态添加一个系统的功能。(transform an input file into .mat for matlab from c++)

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)
