[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。 *ax$R6a#X  
{|bf`  
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： <Zl}u:(w  
enableservice('AutomationServer', true) ~+7q.XL$$K  
enableservice('AutomationServer') #zyEN+  
ESft:3xyw  
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。 +g>)Bur

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： 0ERA(=w5  
1. 在FRED脚本编辑界面找到参考. ~A(fn
:d  
2. 找到Matlab Automation Server Type Library l`4hWs\I  
3. 将名字改为MLAPP _f8Wa u# "

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。 '1_CMr

现在将脚本代码公布如下，此脚本执行如下几个步骤： R<I)}<g(A3  
1. 创建Matlab服务器。 j|c  
2. 移动探测面对于前一聚焦面的位置。 &A)AV<=>T  
3. 在探测面追迹光线 8GgZAu'X  
4. 在探测面计算照度 h(l4\)  
5. 使用PutWorkspaceData发送照度数据到Matlab 5ro^<P0f**  
6. 使用PutFullMatrix发送标量场数据到Matlab中 W_8N?coM  
7. 用Matlab画出照度数据 SvLI%>B

8. 在Matlab计算照度平均值 $F"'=+0  
9. 返回数据到FRED中 bz<f u
