简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 8dO! X.Rb-@ 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: nSW=LjrO~< enableservice('AutomationServer', true) <g1hxfKx5 enableservice('AutomationServer') s!?`T1L ,eTUhK 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 vd[}Gd ,quoRan 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: P0W*C6&71| 1. 在FRED脚本编辑界面找到参考. G_0(

ud0&Oe{ 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 M-1ngI0H; 7s/u(~d) 图 编辑/参考 vbb5f #WZ >33=<~#n 现在将脚本代码公布如下,此脚本执行如下几个步骤: [P&7i57 1. 创建Matlab服务器。 1DE1.1 2. 移动探测面对于前一聚焦面的位置。 ]L9s%]o 3. 在探测面追迹光线 MCS8y+QK 4. 在探测面计算照度 4kBaB 5. 使用PutWorkspaceData发送照度数据到Matlab ^G4Py<s 6. 使用PutFullMatrix发送标量场数据到Matlab中 |G?htZF 7. 用Matlab画出照度数据 Q4+gAS9 8. 在Matlab计算照度平均值 iPd[l{85Z 9. 返回数据到FRED中 7JEbH?lEN -=~| ."O 代码分享: n/Sw P _a6[{_Pc Option Explicit ZUoxMm
