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。 <<4U: '| WY 2>/( 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: g\:(1oY enableservice('AutomationServer', true) &]tZ6 enableservice('AutomationServer') ]2Zl\}GwY ?NWc3 . 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。 V^apDV\AV DxoW,GW 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: lk;4l Z 1. 在FRED脚本编辑界面找到参考. $b OiP 2. 找到Matlab Automation Server Type Library aYW9C<5 3. 将名字改为MLAPP OO#_0qK '*lVVeSiFw ^ZuwUuuf 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。 "n'kv!?\ }LeizbU 图 编辑/参考 a]\l:r m) QV2n 现在将脚本代码公布如下,此脚本执行如下几个步骤: -?nr q <3 1. 创建Matlab服务器。 ZD ~ra7 2. 移动探测面对于前一聚焦面的位置。 0 7b=Zhh 3. 在探测面追迹光线 kn%i#Fz 4. 在探测面计算照度 z[|2od 5. 使用PutWorkspaceData发送照度数据到Matlab maTQ0GX 6. 使用PutFullMatrix发送标量场数据到Matlab中 Q,v/]bXd 7. 用Matlab画出照度数据 [0MNq]gxf 8. 在Matlab计算照度平均值 ^pwT8Bp 9. 返回数据到FRED中 &Ql$7:r sBm)D=Kll 代码分享: Q?xA))0 rel_Z..~ Option Explicit 4M*Z1 ]sLdz^E3D Sub Main Uhs/F:E[A [eLMb)n Dim ana As T_ANALYSIS 6({TG&`!] Dim move As T_OPERATION 1
