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。 y5@#leM xE>jlr? 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: M[eq)a$ enableservice('AutomationServer', true) l<3X:) enableservice('AutomationServer') WZ@hP'Zc ;*{"|l qe 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。 nm#ISueh )wZ;}O 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: ]u5B]ZQnA 1. 在FRED脚本编辑界面找到参考. ?.{SYaS 2. 找到Matlab Automation Server Type Library Ow"e3]}Mt 3. 将名字改为MLAPP ZYS`M?Au sA(d_Yu_ nu(;yIRP 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。 8n&Gn%DvX +DsdzR`Gx, 图 编辑/参考 '@0Z#A k2 _i;v 现在将脚本代码公布如下,此脚本执行如下几个步骤: }yzCq+ 1. 创建Matlab服务器。 ]3D>ai? 2. 移动探测面对于前一聚焦面的位置。 N4HIQ\p 3. 在探测面追迹光线 Wg5<@=x!G 4. 在探测面计算照度 ']bw37_U, 5. 使用PutWorkspaceData发送照度数据到Matlab 0#G@F5; < 6. 使用PutFullMatrix发送标量场数据到Matlab中 @1w[~QlV 7. 用Matlab画出照度数据 A4~-{.w= 8. 在Matlab计算照度平均值 ?<;9=l\Q 9. 返回数据到FRED中 G-6k[-@-v }AW"2<@ 代码分享: s'4O]k` OH
