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。 ?.~1%l ! /fI}QY1 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: i^s Vy enableservice('AutomationServer', true) Ca2r<|uA enableservice('AutomationServer') EZUaYp~M 9[0iIT$q$ 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。 ZEqW*piI mQ[$U 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: {2\Y%Y'}* 1. 在FRED脚本编辑界面找到参考. f}:C~L! 2. 找到Matlab Automation Server Type Library aacy5E 3. 将名字改为MLAPP qE)FQeN "5hk%T' =?i?-6M 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 ? x)^f+:9| -Jd|H*wWo 图 编辑/参考 d ^bSV4 KOcB#UHJ 现在将脚本代码公布如下,此脚本执行如下几个步骤: oRV}Nz7hr 1. 创建Matlab服务器。 `|t,Uc|7! 2. 移动探测面对于前一聚焦面的位置。 Kd\0nf6 3. 在探测面追迹光线 _7c3=f83 4. 在探测面计算照度 p Cz6[*kC 5. 使用PutWorkspaceData发送照度数据到Matlab @C;1e7 6. 使用PutFullMatrix发送标量场数据到Matlab中 JF=R$! 5 7. 用Matlab画出照度数据 :qzg?\( 8. 在Matlab计算照度平均值 '/\ 9. 返回数据到FRED中 IiYL2JS;t| L}Z.FqJ 代码分享: |XyX%5p* FYAEM!dyy Option Explicit wuqe{?
