[技术]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。 jw:4fb  
l%sp[uqcg  
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： p?dGZ2` [I  
enableservice('AutomationServer', true) p/\$P=  
enableservice('AutomationServer') OYqYI!N/  
<Dt/Rad  
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。 c8k6(#\

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： /RA1d
<~$q  
1. 在FRED脚本编辑界面找到参考. ;kyL>mV{  
2. 找到Matlab Automation Server Type Library &%f]-=~  
3. 将名字改为MLAPP s${T*)S@G

U/1[~429  
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。 %nDPM? aO

现在将脚本代码公布如下，此脚本执行如下几个步骤： `}k&HRn  
1. 创建Matlab服务器。 f>\bUmk(  
2. 移动探测面对于前一聚焦面的位置。 %!ER@&1f&  
3. 在探测面追迹光线 5{R#h :  
4. 在探测面计算照度 Se^/V
Vm  
5. 使用PutWorkspaceData发送照度数据到Matlab :/yr(V{  
6. 使用PutFullMatrix发送标量场数据到Matlab中 $L<_uqSk  
7. 用Matlab画出照度数据 fG8}=xH_&  
8. 在Matlab计算照度平均值 X]JpS  
9. 返回数据到FRED中 p:[`%<j0
