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。 Kyl( 4zf#zJw 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: 4QIvxH enableservice('AutomationServer', true) r456M-~ enableservice('AutomationServer') Q ;k_q3 H50nR$$<*Y 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。 eazP'(rc e:7aVOm 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: Q ^ 39Wk@ 1. 在FRED脚本编辑界面找到参考. }f-rWe{gs> 2. 找到Matlab Automation Server Type Library /=r&9P@Ay< 3. 将名字改为MLAPP :cC`wX$ -;~_]t^a q"52-42 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。 Y(A?ib~K R*&3i$S 图 编辑/参考 i;dr(c/ft i-ogeR? 现在将脚本代码公布如下,此脚本执行如下几个步骤: uo%O\}#u9 1. 创建Matlab服务器。 (U.&[B 2. 移动探测面对于前一聚焦面的位置。 'M'LJ.,"/ 3. 在探测面追迹光线 "t\9@nzdX 4. 在探测面计算照度 m",bfZ 5. 使用PutWorkspaceData发送照度数据到Matlab 3QR-8 6. 使用PutFullMatrix发送标量场数据到Matlab中 aPb!-o{ 7. 用Matlab画出照度数据 \Fj4Gy?MW 8. 在Matlab计算照度平均值 F
