[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。 t4K~cK  
gh6d&ucQ^  
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： \C5%\4  
enableservice('AutomationServer', true) XR0O;JN  
enableservice('AutomationServer') N
cCvm#  
8e0."o.6  
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。 htP|3B

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： wNE$6  
1. 在FRED脚本编辑界面找到参考. Q:6VYONN  
2. 找到Matlab Automation Server Type Library eo^/c+FG  
3. 将名字改为MLAPP OlD`uA

mWN#  
&Np9kIMCB  
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。 `Pc3?~>0HH

现在将脚本代码公布如下，此脚本执行如下几个步骤： 8&V_$+U  
1. 创建Matlab服务器。 H(Ms^8Vs~:  
2. 移动探测面对于前一聚焦面的位置。 G%#05jH  
3. 在探测面追迹光线 Lv1{k\aw  
4. 在探测面计算照度 Ml>( tec
 
5. 使用PutWorkspaceData发送照度数据到Matlab 7m5Co>NkuK  
6. 使用PutFullMatrix发送标量场数据到Matlab中 {F|48P;J  
7. 用Matlab画出照度数据 x

8. 在Matlab计算照度平均值 \.e4.[%[2-  
9. 返回数据到FRED中 G[idN3+#
