[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。 abAw#XQ8  
=9Vo[  
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： b^
STegz  
enableservice('AutomationServer', true) U(PW$\l  
enableservice('AutomationServer') nQOzKw<j%  
!F:mDZeY  
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。 C B`7KK

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： !{

1. 在FRED脚本编辑界面找到参考. ^AShy`o^X  
2. 找到Matlab Automation Server Type Library `g_r<EY8/  
3. 将名字改为MLAPP m2H?VY.^K

G!`PP  
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。 76o3Sge:

现在将脚本代码公布如下，此脚本执行如下几个步骤： v8WT?%  
1. 创建Matlab服务器。 Dpwqg3,  
2. 移动探测面对于前一聚焦面的位置。 QI'-I\Co  
3. 在探测面追迹光线 =]5

4. 在探测面计算照度 {+ Ibi{  
5. 使用PutWorkspaceData发送照度数据到Matlab em95ccs'-  
6. 使用PutFullMatrix发送标量场数据到Matlab中 blWtC/!Aq;  
7. 用Matlab画出照度数据 ySB0"bl  
8. 在Matlab计算照度平均值 wMw}3qX$j  
9. 返回数据到FRED中 @U4hq7xzV2
