[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。 uEGPgYY(  
O\Mq<;|7m  
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： +Z<Q^5w@  
enableservice('AutomationServer', true) '
 VEr4&  
enableservice('AutomationServer') tZ j,A%<  
kok^4VV  
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。 qZsddll

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： LZC?383'  
1. 在FRED脚本编辑界面找到参考. <N=p:e,aN,  
2. 找到Matlab Automation Server Type Library q V

3. 将名字改为MLAPP ,Zf!KQw

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。 t<k[W'#

现在将脚本代码公布如下，此脚本执行如下几个步骤： <h_P+ nz  
1. 创建Matlab服务器。 -y*_.Ws9  
2. 移动探测面对于前一聚焦面的位置。 k gu[!hD1  
3. 在探测面追迹光线 +'qX sfc  
4. 在探测面计算照度 >`<2}Me6  
5. 使用PutWorkspaceData发送照度数据到Matlab soq".

6. 使用PutFullMatrix发送标量场数据到Matlab中 99Yo1Q0  
7. 用Matlab画出照度数据 %FyygTb;S  
8. 在Matlab计算照度平均值 G(0y|Eq  
9. 返回数据到FRED中 ff}a <w
