[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。 QeT~s5 H

|WZm  
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： ^:$ShbX"P  
enableservice('AutomationServer', true) djoP`r  
enableservice('AutomationServer') SnX)&>B  
OI0@lSAo<  
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。 N`d%4)|{

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： `*0VN(gf'  
1. 在FRED脚本编辑界面找到参考. G,+3(C  
2. 找到Matlab Automation Server Type Library ~233{vh$=>  
3. 将名字改为MLAPP 45BpZ~-

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。 *yHz#u'

1. 创建Matlab服务器。

2. 移动探测面对于前一聚焦面的位置。 *6][[)(  
3. 在探测面追迹光线 9Y:.v@:}0  
4. 在探测面计算照度 Gh6U<;V?*  
5. 使用PutWorkspaceData发送照度数据到Matlab X]2x0  
6. 使用PutFullMatrix发送标量场数据到Matlab中 JoG(Nk

7. 用Matlab画出照度数据 eV

8. 在Matlab计算照度平均值 |}8SjZcQW  
9. 返回数据到FRED中 pKLNBR|
