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。 9k=U0]!ch f.aB?\"f6 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: d%#!nq{vd enableservice('AutomationServer', true) "'z,[v50& enableservice('AutomationServer') Sc4obcw% .)"_Q/q
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。 n*vTVt)dJ ~|y^\U@ 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: Ge^zX$.' 1. 在FRED脚本编辑界面找到参考. )h>\05|T 2. 找到Matlab Automation Server Type Library 7K>D@O 3. 将名字改为MLAPP QQg8+{> E ;BPN kCaO\#ta 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 vU_d=T%$ }J ei$0x 图 编辑/参考 W_[|X}lWP &v5G92 现在将脚本代码公布如下,此脚本执行如下几个步骤: ]6$,IKE7 1. 创建Matlab服务器。 j4~7akG 2. 移动探测面对于前一聚焦面的位置。 8)^B32 3. 在探测面追迹光线 w(76H^e 4. 在探测面计算照度 Q00R<hu@F 5. 使用PutWorkspaceData发送照度数据到Matlab Jv_.itc 6. 使用PutFullMatrix发送标量场数据到Matlab中 _ztZ>' 7. 用Matlab画出照度数据 csH2_+uG 8. 在Matlab计算照度平均值 FAQr~G} 9. 返回数据到FRED中 hpbwZ !dU9sB2 代码分享: h>}ax\h %
