[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。 +f5|qbX/\  
z-9@K<`H  
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： F4P=Wz]  
enableservice('AutomationServer', true) 0^%\! Xxq  
enableservice('AutomationServer') 8(AI|"A"-  
g(X-]/C{  
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。 bIvF5d>9#K

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： \VL_  
1. 在FRED脚本编辑界面找到参考. Z)JJ-V!  
2. 找到Matlab Automation Server Type Library 7!-3jU@m  
3. 将名字改为MLAPP i|`b2msvd

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。 #

现在将脚本代码公布如下，此脚本执行如下几个步骤： #F>7@N:5  
1. 创建Matlab服务器。 d]3c44kkK{  
2. 移动探测面对于前一聚焦面的位置。 "7w

3. 在探测面追迹光线 8|-j]   
4. 在探测面计算照度 XwZ~pY ~  
5. 使用PutWorkspaceData发送照度数据到Matlab \IL;}D{  
6. 使用PutFullMatrix发送标量场数据到Matlab中 6[b?ckvi  
7. 用Matlab画出照度数据 t^8ii  
8. 在Matlab计算照度平均值 Mz?xvP?z  
9. 返回数据到FRED中 jb~W(8cj
