[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。 1oVjx_I5y  
sO;]l"{<  
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： $At,D.mGkb  
enableservice('AutomationServer', true) B;6N.X(K  
enableservice('AutomationServer') (+=TKI<=  
f[;l7  
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。 *]u

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： Z7@~#)3  
1. 在FRED脚本编辑界面找到参考. h=`1sfz  
2. 找到Matlab Automation Server Type Library {W5

3. 将名字改为MLAPP <Ky6|&!

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。 DdG*eKC

现在将脚本代码公布如下，此脚本执行如下几个步骤： YJ[Jo3M@j0  
1. 创建Matlab服务器。 =nTNL.SX  
2. 移动探测面对于前一聚焦面的位置。 $>M A  
3. 在探测面追迹光线 {+.ai8  
4. 在探测面计算照度 GSh~j-C'  
5. 使用PutWorkspaceData发送照度数据到Matlab x.:k0;%Q  
6. 使用PutFullMatrix发送标量场数据到Matlab中 |!=KLJUA  
7. 用Matlab画出照度数据 N`Q[OFe  
8. 在Matlab计算照度平均值 nOE 1bf^l  
9. 返回数据到FRED中 hV6
