[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。 5Yg'BkEr  
wcrCEX=I>{  
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： tURu0`](  
enableservice('AutomationServer', true) m~iXl,r  
enableservice('AutomationServer') zU5v /'h>d  
#3i3G(mQ  
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。 h9t$Uz^N

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： k0OYJ/  
1. 在FRED脚本编辑界面找到参考. }~YA5^VQ$  
2. 找到Matlab Automation Server Type Library qk%;on&`  
3. 将名字改为MLAPP k$

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。 AHD=<7Rs

现在将脚本代码公布如下，此脚本执行如下几个步骤： &C`Gg<  
1. 创建Matlab服务器。 I,E?h?6Y  
2. 移动探测面对于前一聚焦面的位置。 QE^$=\l0  
3. 在探测面追迹光线 9&$y}Y  
4. 在探测面计算照度 R[zpD%CI  
5. 使用PutWorkspaceData发送照度数据到Matlab |6.l7u?d  
6. 使用PutFullMatrix发送标量场数据到Matlab中 LoURC$lS  
7. 用Matlab画出照度数据 "|x^|n8i  
8. 在Matlab计算照度平均值 J4k=A7^N  
9. 返回数据到FRED中 W,K;6TZhh
