[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。 jRV/A!4  
R{T$[$6S  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： >[*qf9$  
enableservice('AutomationServer', true) &@YmA1Yu)E  
enableservice('AutomationServer') x-3\Ls[I  
/&94 eC  
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。 H<N,%G

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： Y:a]00&)#Y  
1. 在FRED脚本编辑界面找到参考. pz>>)c`  
2. 找到Matlab Automation Server Type Library VW4r{&rS  
3. 将名字改为MLAPP HyWCMK6b

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。 Z?QC!bW

现在将脚本代码公布如下，此脚本执行如下几个步骤： c0u^zH<  
1. 创建Matlab服务器。 [ibu/W$  
2. 移动探测面对于前一聚焦面的位置。 | %Vh`HT  
3. 在探测面追迹光线 =C.$ UX  
4. 在探测面计算照度 E^eVvP4uC@  
5. 使用PutWorkspaceData发送照度数据到Matlab n7-6- #  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Y0-n\|  
7. 用Matlab画出照度数据 )Z9>$V$j  
8. 在Matlab计算照度平均值 ,\%c^,HLJ  
9. 返回数据到FRED中 )hfpwdQ
