[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。 $ A-b vL  
-Ubj6 t_K  
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： mKg@W;0ML  
enableservice('AutomationServer', true) R+$8w2#  
enableservice('AutomationServer') ij&p4  
s"0b%0?A  
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。 ~ |,e_ zA  
l@d gJ  
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： %XXkVK`  
1. 在FRED脚本编辑界面找到参考. f@:CyB GQ  
2. 找到Matlab Automation Server Type Library {B yn{?w  
3. 将名字改为MLAPP {.#zHL ;

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。 ,bSVVT-b

现在将脚本代码公布如下，此脚本执行如下几个步骤： ~Y/z=^  
1. 创建Matlab服务器。 <
~%t$:  
2. 移动探测面对于前一聚焦面的位置。 2Yyb#Ow  
3. 在探测面追迹光线 o*7yax  
4. 在探测面计算照度 gB CC  
5. 使用PutWorkspaceData发送照度数据到Matlab = ?N^>zie  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Ww87  
7. 用Matlab画出照度数据 T=? bdIl  
8. 在Matlab计算照度平均值 u"F;OT\>g  
9. 返回数据到FRED中 *=^[VV!
