[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。 ;BejFcb  
ofj7$se  
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： aq0J }4U  
enableservice('AutomationServer', true) ?K|PM<A  
enableservice('AutomationServer') {jJUS>  
+\\*Iy'xK  
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。 2JUX29rER

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： e
l;^cMY  
1. 在FRED脚本编辑界面找到参考. K:465r:  
2. 找到Matlab Automation Server Type Library rV[#4,}PF  
3. 将名字改为MLAPP 8y/YX

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。 0F0V

现在将脚本代码公布如下，此脚本执行如下几个步骤： S%kE<M?  
1. 创建Matlab服务器。 05=O5<l  
2. 移动探测面对于前一聚焦面的位置。 F,%q

3. 在探测面追迹光线 f?2Y np=@  
4. 在探测面计算照度 G5kM0vs6L  
5. 使用PutWorkspaceData发送照度数据到Matlab L!3{ASIN0  
6. 使用PutFullMatrix发送标量场数据到Matlab中 "z=A=~~<{  
7. 用Matlab画出照度数据 %0Ulh6g;Dt  
8. 在Matlab计算照度平均值 |.*),t3 (w  
9. 返回数据到FRED中 d3&gHt2
