[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。 +?o!"SJ  
%(/E `  
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： pS ](Emn`.  
enableservice('AutomationServer', true) iv *$!\Cd  
enableservice('AutomationServer') @NRN#~S,_]  
<7\j\`  
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。 \j`0f=z_

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： HdqB B
  
1. 在FRED脚本编辑界面找到参考. {k_\1t(/  
2. 找到Matlab Automation Server Type Library ?o;ip  
3. 将名字改为MLAPP [:cD

: "|/  
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。 *O~y6|U?

现在将脚本代码公布如下，此脚本执行如下几个步骤： c#{lXS^  
1. 创建Matlab服务器。 vYm:V:7Y2  
2. 移动探测面对于前一聚焦面的位置。 IRm}?hHf  
3. 在探测面追迹光线 :$b`n  
4. 在探测面计算照度 @c]KHWI  
5. 使用PutWorkspaceData发送照度数据到Matlab  k;+TN9  
6. 使用PutFullMatrix发送标量场数据到Matlab中 72OqXa*  
7. 用Matlab画出照度数据 A,<5W }  
8. 在Matlab计算照度平均值 *HR pbe2  
9. 返回数据到FRED中 &S{r;N5u
