[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。 mA=i)Ga  
={xE!"  
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： uPl\I6k  
enableservice('AutomationServer', true) #Q`dku%V:  
enableservice('AutomationServer') O|M{-)  
SrK)t.oK  
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。 k>g_Z`%<

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： -xA2pYz"  
1. 在FRED脚本编辑界面找到参考. |VNnOM  
2. 找到Matlab Automation Server Type Library 07^iP>?  
3. 将名字改为MLAPP }=]M2}

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。 [6XF=L,!

现在将脚本代码公布如下，此脚本执行如下几个步骤： J\M>33zu  
1. 创建Matlab服务器。 7*Ej.

2. 移动探测面对于前一聚焦面的位置。 *5^Q7``  
3. 在探测面追迹光线 ~,B5Hc 2  
4. 在探测面计算照度 DuHu\>f<S  
5. 使用PutWorkspaceData发送照度数据到Matlab j4R(B  
6. 使用PutFullMatrix发送标量场数据到Matlab中 4QIX19{"  
7. 用Matlab画出照度数据 ?3.b{Cq{-  
8. 在Matlab计算照度平均值 #ka

9. 返回数据到FRED中 OD6\Mr2=
