[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。 BS6UXAf{|Z  
IPIas$  
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： )J['0DUrZK  
enableservice('AutomationServer', true) YpGG^;M$  
enableservice('AutomationServer') ~zcHpxO^W  
{hE\ECT-  
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。 ;1wRo`RD

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： 3Dm`8Xt  
1. 在FRED脚本编辑界面找到参考. G!^}z(Mgi  
2. 找到Matlab Automation Server Type Library sK&[sN33  
3. 将名字改为MLAPP $O)fHD'

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。 2<  "-

现在将脚本代码公布如下，此脚本执行如下几个步骤： tr<iFT}C  
1. 创建Matlab服务器。 j~'a %P  
2. 移动探测面对于前一聚焦面的位置。 C.& R,$  
3. 在探测面追迹光线 8d!t"oj68  
4. 在探测面计算照度 o~(/Twxam  
5. 使用PutWorkspaceData发送照度数据到Matlab : }q~<  
6. 使用PutFullMatrix发送标量场数据到Matlab中 z|^+
uL  
7. 用Matlab画出照度数据 #7Pnw.s3zz  
8. 在Matlab计算照度平均值 _T{ "F  
9. 返回数据到FRED中 { +$zgg
