[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。 \2eFpy(  
2<.Vv\ =  
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： HU3Vv<lz  
enableservice('AutomationServer', true) 7dhn'TW  
enableservice('AutomationServer') L9'-  
:A$wX$H01  
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。 'Fzuc^G(d  
$WD +Q@6  
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： wR1K8b".DC  
1. 在FRED脚本编辑界面找到参考. sRil>6QR  
2. 找到Matlab Automation Server Type Library }Ch[|D=Wd6  
3. 将名字改为MLAPP rH^/8|}&s

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。 '!j(u@&!

现在将脚本代码公布如下，此脚本执行如下几个步骤： Oylp:_<aT  
1. 创建Matlab服务器。 b2%blQgo  
2. 移动探测面对于前一聚焦面的位置。 *%f3rvt7@)  
3. 在探测面追迹光线 a j_:|]j  
4. 在探测面计算照度 .kzms  
5. 使用PutWorkspaceData发送照度数据到Matlab kBUufV
~  
6. 使用PutFullMatrix发送标量场数据到Matlab中 8|_K  
7. 用Matlab画出照度数据 o9^$hDs,si  
8. 在Matlab计算照度平均值 GfQ^@Tl  
9. 返回数据到FRED中 $u-lo|
