[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。 |lu@rN  
A{T>Aac  
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： olXfR-2>1  
enableservice('AutomationServer', true) i=pfjC  
enableservice('AutomationServer') MBU4Awj  
EU'rdG*t/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。 qzLD

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： 9;`hJ!r  
1. 在FRED脚本编辑界面找到参考. 7uF @Xh  
2. 找到Matlab Automation Server Type Library 0m\( @2E  
3. 将名字改为MLAPP /+. m.TF

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。 A_2lG!! 6

现在将脚本代码公布如下，此脚本执行如下几个步骤： P=y1qqC  
1. 创建Matlab服务器。 O0bOv S  
2. 移动探测面对于前一聚焦面的位置。 #T`1Z"h<  
3. 在探测面追迹光线 -*-"kzgd  
4. 在探测面计算照度 m")p]B&i=  
5. 使用PutWorkspaceData发送照度数据到Matlab ,W/Y@Sc
C  
6. 使用PutFullMatrix发送标量场数据到Matlab中 R mo'3  
7. 用Matlab画出照度数据 300[2}Y]  
8. 在Matlab计算照度平均值 DiZv sc  
9. 返回数据到FRED中 Bi"cWO
