Examples
- Secondly , three algorithms is presented to deal with different mechanism , based on it , a method of using the c + + math library of matlab is presented to simplify the solving process in the data processing
其次，针对不同机构的特点，采用了三种不同的算法来处理运动仿真数据，在此基础上，提出了在数据处理部分使用matlabc + +数学函数库进行求解的方法，简化了求解的过程 - In the module of data management , the ado programming technology was combined with access database to sort and manage the data . in data processing module , the matlab and vc + + co - programming scheme was presented in which the original data were transformmed geometrically so that the 3d data model was established . the graphical display module was developed on the base of opengl and vc platform with which the 2d geological drawings and 3d geological drawings could be accomplished
在数据管理模块中，选用ado数据库开发技术，结合使用access数据库对数据进行分类管理与存储；在数据处理模块中，提出了利用matlab vc ~ ( + + )联合编程的方案，通过使用matlabc c ~ ( + + )数学函数库完成了反演数据的几何变换以及三维数据模型的建立；在图形显示模块中，以图形接口opengl作为绘图语言，在vc平台下进行开发，实现了二维地质图件和三维地质图件的绘制。 - It really provides convenience to evaluate and optimize the design result . 3 ) vibration analysis has been fulfilled by calling some math libraries and graphic libraries in matlab to plot graphics such as velocity - time , displacement - velocity , step response , impulse response , gain - frequency and phase - frequency . we can know the capabilities of the spring system from the graphics
3 、在matlab环境下调用相应的数学函数库和图形库对设计的弹簧进行分析，绘制弹簧加载后系统的速度-时间响应曲线、速度-位移响应曲线、阶跃响应曲线、脉冲响应曲线、增益-频率响应曲线和相角-频率响应曲线，根据曲线来分析系统的各项性能。 - With fault diagnosis of rotating machinery as example , the similarity - based generalized rough sets theory was applied to reduction of incomplete decision system to find necessary conditions for diagnosis . based on the optimal decision system obtained from the reducts , bp neural network was designed for fault identification . the application of the reducted decision system to the neural fault classifier indicated that rough sets based reduction reduces the dimension of input to neural network , and raise
