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。 K8Q3~bMf Oet+$ b 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: vQ]d?Tp enableservice('AutomationServer', true) x NjQ"'i8 enableservice('AutomationServer') shw"TF>?zG $8xb|S[ 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。 W+/_0GgQ3 PR]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: YSB=nd_ 1. 在FRED脚本编辑界面找到参考. &q@brX<,= 2. 找到Matlab Automation Server Type Library vS)>g4 3. 将名字改为MLAPP #]6{>n1*+w 6M.|W; !\[JWN@v 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。 kiyc ^s UfPHV%Wd 图 编辑/参考 gnjhy1o s5rD+g]E` 现在将脚本代码公布如下,此脚本执行如下几个步骤: jw9v&/- 1. 创建Matlab服务器。 o<%0|n_O& 2. 移动探测面对于前一聚焦面的位置。 M2N8?Ycv3 3. 在探测面追迹光线 f*B-aj# 4. 在探测面计算照度 92t.@!m` 5. 使用PutWorkspaceData发送照度数据到Matlab !yxqOT- 6. 使用PutFullMatrix发送标量场数据到Matlab中 g&y^ r/ 7. 用Matlab画出照度数据 vsZ?cd 8. 在Matlab计算照度平均值 &b`W<PAc?4 9. 返回数据到FRED中 I8j:{*h jeJgDAUv 代码分享: v&'#Gg 5QLK Option Explicit gK9d `5 5K 2K'ZkI Sub Main tV`=o$` J-Tiwl Dim ana As T_ANALYSIS 1kKfFpN Dim move As T_OPERATION _1&Ar4: Dim Matlab As MLApp.MLApp xE
