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。 RMrt4:-DI "ChBcxvxb: 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: %F/tbXy{ enableservice('AutomationServer', true) Yc5$915 enableservice('AutomationServer') AU$5"kBE 1X9sx&5H 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 a+BA~|u^ 9hp0wi@W} 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: >zhbipA 1. 在FRED脚本编辑界面找到参考. wYawG$@_ 2. 找到Matlab Automation Server Type Library 2Uk8{d 3. 将名字改为MLAPP *AN#D?X_ {DO9{96w4 9_/1TjrDN 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。 IH0^*f JT-Zo OZ 图 编辑/参考 p_(hM&>C ?^+|V,< 现在将脚本代码公布如下,此脚本执行如下几个步骤: BPOWo8TqD^ 1. 创建Matlab服务器。 =gqZ^v&5U 2. 移动探测面对于前一聚焦面的位置。 \%^3Izsc 3. 在探测面追迹光线 Zj^H3h 4. 在探测面计算照度 V7v,)a" L 5. 使用PutWorkspaceData发送照度数据到Matlab FxT
