基于vb.net的autocad二次开发关于图形动态装拆模拟能使二维图形三维图形三维曲面绘制spline样条曲线路径往复运动(Vb.net based on secondary development of autocad Assembly and Disassembly on the graphical simulation of dynamic two-dimensional graphics will enable three-dimensional surface rendering of three-dimensional graphics spline spline curve the path of reciprocating movement)

有限单元法及程序设计（第二版），天津大学刘尔烈，非常经典的fortran学习材料(Finite element method and program design (Second Edition),Tianjin University, Liu Erlie, a very classic FORTRAN learning material)

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 )

可以得到很精确的幅值、频率、相位估计，用于信号特征提取、信号消噪，有循环检测，周期性检测。( You can get a very accurate amplitude, frequency, phase estimation, For feature extraction, signal de-noising, There are cycle detection, periodic testing.)

一个很好的mpc例子，用mpc来控制flywheel。(A good example of mpc, the mpc to control the flywheel.)

关于拉曼光谱基线去除的程序,大家可以试试,文章发在了Analyst上,RSC.具体的信息可以从代码里面找到.(This is a programme about Roman spectroscopy, it can be ured for basline eleminated. If you are interesting about it, download it!)

八位串行乘法器 缺点：乘法功能是正确的，但计算一次乘法需要8个周期，因此可以看出串行乘法器速度比较慢、时延大。 优点：该乘法器所占用的资源是所有类型乘法器中最少的，在低速的信号处理中有广泛的使用。(Eight bit serial multiplierDisadvantages: the multiplication function is correct, but the computation of one multiplication requires 8 cycles, so it can be seen that the serial multiplier is slow and time-consuming. Advantages: the multiplier occupies the smallest number of resources in all types of multipliers, and is widely used in low speed signal processing.)

说明：  最优化处理课本的第四章程序源码，可以下载后和课本内容一起学习。(The fourth chapter of the program source code that optimizes the processing of the textbook can be downloaded and learned together with the textbook content.)
