17794_结构分析的有限元法与Matlab程序设计源程序

说明：  对IQ接收器最重要的两个参数,即I和Q两路分量之间的幅度一致性和相位正交性,可采 用如下办法计算:把I、Q 两路信号分别作FFT ,找出频域内信号的幅度,即可算得两路分量的幅度一 致性 把I、Q两路信号合成一个复数信号,作FFT ,对得到的频谱求镜像抑制比(即频域内的信号与信号镜像的幅度比) ,通过镜像抑制比和幅度一致性,可求出接收机的I和Q两路分量之间的相位正交性。(IQ receiver for the two most important parameters, namely I and Q components of two-way consistency between the amplitude and phase orthogonality may be adopted calculated using the following method: to I, Q 2 signals, respectively for FFT, to find a frequency domain signal amplitude, can be considered as two-way component caused by the range of 1 the I, Q 2 signals into one complex signal for FFT, the spectrum demand of the received image rejection ratio (ie, frequency domain signal and magnitude of the signal mirror ratio), through the image rejection ratio and extent of consistency, the receiver can be derived I and Q phase between the two-way component orthogonality.)

说明：  用迭代法求 x=根号a。求平方根的迭代公式为：X(n+1)=(Xn+a/Xn) /2。(Iterative method is used to find x = root a. The iteration formula for finding square root is X(n+1)=(Xn+a/Xn)/2.)

说明：  第1例到第6例的源描述都是从第8例的程序包中 提取出来的,不能单独编译,这些例子的编译与 模拟请参考第8例.(Example No. 1 to the first six cases are the source described in Example 8 from the first package to extract it and can not be a separate compiler, which compiler and simulation examples please refer to the first eight cases.)

Fuzzy PSO算法仿真源代码,实现模糊蚁群优化算法的仿真。(Fuzzy PSO algorithm )

说明：  实现对逆变器的三相电流、三相电压、三相IGBT温度、三相的频率等采样，涉及了应用层程序和底层程序(Sampling of three-phase current, three-phase voltage, three-phase IGBT temperature and three-phase frequency of inverters is realized, which involves application layer program and bottom layer program.)

说明：  这是一个带有FEAPPV的测试库。有限元分析程序（FEAP）用有限元法求解一般问题。问题大小由每台计算机的主内存量控制。(This is a test repository with FEAPpv. Finite Element Analysis Program - (FEAP) for solution of general problem classes using the finite element method. Problem size is controlled by the amount of main memory in each computer.)

定义循环队列，完成队列的基本操作：入队和出队等(Defined circular queue, the queue to complete the basic steps: into the team and the teams)

c++模板源码中的第一章节memory，方便你学习时参考，应该会对你有所帮助(c++ template source in the first section of memory, easy reference when you learn, it should be will help you)

算法图解中文版全文，实例丰富，图文并茂，以简明易懂的方式阐明了算法(Grokking Algorithms is a fully illustrated, friendly guide that teaches you how to apply common algorithms to the practical problems you face every day as a programmer.)

包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角，进行波形数据分析,这是第二能量熵的matlab代码。( It comprises aircraft flight attitude control, such as slip angle, tilt angle, roll angle, pitch angle, Waveform data analysis, This is the second energy entropy matlab code.)
