[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。 .wmqaLd%  
6`vW4]zu  
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： B,&QI&k`~  
enableservice('AutomationServer', true) 7>f"4r_r6<  
enableservice('AutomationServer') ?20R\ ]U  
?;H}5>^8P  
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。 "Zx<hL*  
~A1!!rJX  
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： V#5$J Xp  
1. 在FRED脚本编辑界面找到参考. $:\`E56\  
2. 找到Matlab Automation Server Type Library @OGG]0 J  
3. 将名字改为MLAPP P-nhG  
Dx`-h#  
q3#+G:nh  
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。 &r~s3S{pQ

现在将脚本代码公布如下，此脚本执行如下几个步骤： 15q^&l[Q  
1. 创建Matlab服务器。 jd,i=P%  
2. 移动探测面对于前一聚焦面的位置。 ZHa>8x;Mjl  
3. 在探测面追迹光线 6}?d%K  
4. 在探测面计算照度 01n132k  
5. 使用PutWorkspaceData发送照度数据到Matlab cs?WE9N  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ><Zu+HX  
7. 用Matlab画出照度数据 lSW'qgh  
8. 在Matlab计算照度平均值 k].swvIi  
9. 返回数据到FRED中 aidQ,(PDj
