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。 j 7O!uUQQ o2]Np~`g, 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: k!+v*+R+V enableservice('AutomationServer', true) K@osD7- enableservice('AutomationServer') _XrlCLp: d 6BQq|:U 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。 33hP/p% ~e){2_J&n 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: w`#9Re 1. 在FRED脚本编辑界面找到参考. k4:=y9`R}$ 2. 找到Matlab Automation Server Type Library YVz,P_\(m 3. 将名字改为MLAPP ^tjM1uaZ5( >%t5j?p %/s+-j@s: 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。 ;\/RgN nAj +HLO 图 编辑/参考 Q5Mn= 8<EU|/O 现在将脚本代码公布如下,此脚本执行如下几个步骤: 1x+w|h 1. 创建Matlab服务器。 y,<\d/YY@ 2. 移动探测面对于前一聚焦面的位置。 *;T HD> 3. 在探测面追迹光线 akgvV~5 4. 在探测面计算照度 N{!@M_C^%R 5. 使用PutWorkspaceData发送照度数据到Matlab 8 }Maj 6. 使用PutFullMatrix发送标量场数据到Matlab中 <2I<Z'B,e 7. 用Matlab画出照度数据 reoCyP\!! 8. 在Matlab计算照度平均值 }\ya6Gi8 9. 返回数据到FRED中 w~e$ul(IQM 5@i(pVWZ 代码分享: C7
