case_study_3

用matlab编写的，有限元三维梁单元的单元刚度矩阵计算程序，各节点6个自由度。(prepared by the three-dimensional finite element beam element of the element stiffness matrix calculation program, the 6-DOF nodes.)

说明：  详细的介绍matlab的使用，适合初学者使用~ 一本好的教材~(The detailed introduction of matlab use, is suitable for beginners use ~ A good textbook ~)

画出下述情况下均匀线阵方向图 1）计算来波方向为0度方向图 2）画出来波方向为45度时的方向图 3）画出来波方向为0度，幅度取分贝数：20log***（单位为dB）时的方向图 4）画出来波方向为0度，随着阵元数的增加，当N=16，N=32时的方向图，并对方向图的变化情况进行说明(Draw the following conditions uniform linear array 1) calculation of wave direction is 0 degrees direction diagram 2) draw out the wave direction is 45 degrees direction map 3) draw out the wave direction is 0 degrees, and amplitude decibels: 20log*** (unit dB) when the direction of FIG. 4) draw out the wave direction is 0 degrees, with the increase of the number of array elements, when N=16, N=32 pattern, and the change of direction is described )

随便编写的，我刚学matlab图像处理，这是我的学习程序(Just write, I just learning matlab image processing, this is my learning process)

电力系统仿真，简洁，高效，有三机九节点、14节点、风机、光伏等模型(Power system simulation, simple and efficient)

各种kalman滤波器的设计，小波包分析提取振动信号中的特征频率，最大信噪比的独立分量分析算法。( Various kalman filter design, Wavelet packet analysis to extract vibration signal characteristic frequency, SNR largest independent component analysis algorithm.)
