[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。 ^ytrK Q  
|df Pki{  
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： eByz-,{P  
enableservice('AutomationServer', true) =nS3p6>rZ  
enableservice('AutomationServer') *&W"bOMH*  
HC8e>kP9b  
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。 WH}y"W

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： Llo"MO*sr  
1. 在FRED脚本编辑界面找到参考. F>l] 9!P|m  
2. 找到Matlab Automation Server Type Library R n[cW5Y<  
3. 将名字改为MLAPP d0ksG$

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。 p2](_}PK

现在将脚本代码公布如下，此脚本执行如下几个步骤： W!(zT6#  
1. 创建Matlab服务器。 \b x$i*  
2. 移动探测面对于前一聚焦面的位置。 "+s++@ z  
3. 在探测面追迹光线 Hn"RH1Zy  
4. 在探测面计算照度 oc`H}Wvn  
5. 使用PutWorkspaceData发送照度数据到Matlab Otuf]B^s  
6. 使用PutFullMatrix发送标量场数据到Matlab中 (A#^l=su  
7. 用Matlab画出照度数据 oPM96 (  
8. 在Matlab计算照度平均值 t{96p77)=  
9. 返回数据到FRED中 Yq KCeg
