[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。 MLVB^<qkeH  
m7]hJ,0  
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： @ CsV]97`  
enableservice('AutomationServer', true) V-O(U*]  
enableservice('AutomationServer') VkmRh,T  
g;p)n  
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。 |lQ;ALH!

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： "u^EleE!  
1. 在FRED脚本编辑界面找到参考. yOXO)u1n  
2. 找到Matlab Automation Server Type Library C"<s/

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。 (-yl|NFBw

现在将脚本代码公布如下，此脚本执行如下几个步骤： #XIc "L)c  
1. 创建Matlab服务器。 O_,O,1  
2. 移动探测面对于前一聚焦面的位置。 5fjd{Y[k  
3. 在探测面追迹光线 +=@
^i'  
4. 在探测面计算照度 .QWhK|(.!  
5. 使用PutWorkspaceData发送照度数据到Matlab j.?:Gaab?#  
6. 使用PutFullMatrix发送标量场数据到Matlab中 c=p=-j=.J  
7. 用Matlab画出照度数据 Rs;15@t@  
8. 在Matlab计算照度平均值 D9ufoa&ua  
9. 返回数据到FRED中 u</8w&!
