smallest

说明：  编程教程，帮助入门学者学习建模，从初级开始，逐步深化，非常有帮助(Programming tutorials, help beginners learn modeling, from the beginning, gradually deepen, very helpful)

最优化的bfgs算法，是采用matlab编程(BFGS optimization algorithm, using matlab programming)

运用线性矩阵不等式(LMI)求解鲁棒优化问题。该LMI不等式求解代码，更具有一般性，结合matlab中help命令,能够方便的对新的LMI问题求解(This programme code is useful for the common optimization problem, combined with the description of matlab help statement, a new LMI problem can be easy to solve. )

包含优化类的几个简单示例程序，包括四元数的各种计算,一个计算声子晶体结构的一维传递矩阵法。( Optimization class contains several simple sample programs, Including quaternion various calculations, A one-dimensional transfer matrix method to calculate the phonon crystal structure.)

说明：  分数阶傅里叶变换计算方面的文章，另附程序清单(Fractional Fourier transform calculation of the article, followed the list of procedures)

Galileo单频定位程序，能基于rinex文件实现高精度定位，供编写时参考(Galileo single-frequency positioning program can achieve high-precision positioning based on RINEX file for reference when writing.)

说明：  关闭OFDM信号子载波，画出OFDM信号频谱图，查看旁瓣泄露情况(Close OFDM signal sub-carrier OFDM signal spectrum plot, view the situation sidelobe leakage)

对GID软件的数据进行预处理,用于有限元计算(preprocessing to gid software output data file)

很好的算法，可广泛用于各行业（如工控）计算组态(It s a very good arithmetic that can be used at many industries.such as industry control,for caculation configuration.)
