integrator

说明：  FR共轭梯度算法求极小值。y为给定函数，x为函数变量，x0为搜索起始点 返回值fm为极小值，xm为极小值点(FR conjugate gradient algorithm for the minimum. y for a given function, x as a function of variables, x0 the starting point for the search to return to the value of fm for the minimum, xm for the minimum point)

在理想的信道状态条件下，对MIMO-OFDM系统进行仿真，包括信道估计，调制，解调，信道编解码等(In an ideal channel state conditions, the MIMO-OFDM system is simulated, including channel estimation, modulation, demodulation, channel coding and decoding)

K-means K均值聚类算法，不是用工具箱编的，对随机产生的数据进行聚类。压缩文件包括m函数、包含主程序和子函数的word文档。(K-means clustering algorithm, not with the toolbox series of randomly generated data clustering.M functions including compressed files, containing the main program and subroutines word document.)

本程序为第八章的第二个算例，采用平面梁单元计算两铰抛物线拱的在初始条件下自由振动，并对时程曲线结果进行FFT变换.(failed to translate)

This function creates a figure with multiple Tabs.The number of tabs can be changed and they are distributed evenly across the top of the figure. Content is provided for the first 5 tabs to demo the program. The demo uses the screen size to adjust the size of the figure.
