[分享]FRED如何调用Matlab [复制链接]

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。 xo^b&ktQd  
<)Dj9' _J  
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： w7L{_aom  
enableservice('AutomationServer', true) )$2QZ qX  
enableservice('AutomationServer') -_g0C^:<,  
\doUTr R  
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\{ l

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： 4

1. 在FRED脚本编辑界面找到参考.

2. 找到Matlab Automation Server Type Library CO/]wS  
3. 将名字改为MLAPP (MM]N=Tw4

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。 mY|)KJ

1. 创建Matlab服务器。 P8:dU(nlW  
2. 移动探测面对于前一聚焦面的位置。 ~7w"nIs<c  
3. 在探测面追迹光线 RMV/&85?y  
4. 在探测面计算照度 ktXM

5. 使用PutWorkspaceData发送照度数据到Matlab +HpA:]#Y  
6. 使用PutFullMatrix发送标量场数据到Matlab中 {lzWrUGO  
7. 用Matlab画出照度数据 ^oz3F]4,g  
8. 在Matlab计算照度平均值 Wtd/=gmiI  
9. 返回数据到FRED中 &&8x%Pml
