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。 0^RXGN lS'-xEv? 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: 8=Z9T<K enableservice('AutomationServer', true) t`,`6@d enableservice('AutomationServer') (KF=On;=Y @)4]b+8Z 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。 MgNU`` D(H>R&b! 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: <F=xtyl7 1. 在FRED脚本编辑界面找到参考. 7|[mz> "d 2. 找到Matlab Automation Server Type Library :X]itTrGs 3. 将名字改为MLAPP JaL%qco "t_-f7fS7 ?)1{)Erf8x 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。 3YFU*f, s8#X3Rp 图 编辑/参考 ^WNrGF <c,u3cp 现在将脚本代码公布如下,此脚本执行如下几个步骤: A3S<..g2 1. 创建Matlab服务器。 YGPy@-,E 2. 移动探测面对于前一聚焦面的位置。 )8UWhl= 3. 在探测面追迹光线 fIwV\,s 4. 在探测面计算照度 Hqn#yInA7~ 5. 使用PutWorkspaceData发送照度数据到Matlab /gu%:vq 6. 使用PutFullMatrix发送标量场数据到Matlab中 (;57 Vw 7. 用Matlab画出照度数据 70;Jl).\{ 8. 在Matlab计算照度平均值 lAJxr8 . 9. 返回数据到FRED中 '_/Bp4i cdZ~2vk 代码分享: A0q|J/T E7Y`|nT Option Explicit s+EAB{w$ /i-J&*6_ Sub Main D*F4it. - qy6Un+ Dim ana As T_ANALYSIS g47-db"5 Dim move As T_OPERATION -!N&OZ+R
