[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。 lpq)vKM}^  
RGu`Jk  
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： fMpxe(  
enableservice('AutomationServer', true) #!0=I s^  
enableservice('AutomationServer') ZZs@P#]  
5VS};&f  
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。 jo-2D[Q{

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： T}}T`Ce  
1. 在FRED脚本编辑界面找到参考. Vjdu9Ez  
2. 找到Matlab Automation Server Type Library ._E 6?  
3. 将名字改为MLAPP |2Vhj<6

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。 @=7[KMb

现在将脚本代码公布如下，此脚本执行如下几个步骤： =:M/hM)#  
1. 创建Matlab服务器。 z|F38(%JJN  
2. 移动探测面对于前一聚焦面的位置。 sH'IA~7  
3. 在探测面追迹光线 6%a9%Is!O  
4. 在探测面计算照度 1^ijKn@6  
5. 使用PutWorkspaceData发送照度数据到Matlab %jE0Z4\  
6. 使用PutFullMatrix发送标量场数据到Matlab中 8|LU=p`y'  
7. 用Matlab画出照度数据 !.G knDT  
8. 在Matlab计算照度平均值 }ed{8"bj  
9. 返回数据到FRED中 +C}s"qrb@
