[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。 9k=U0]!ch  
f.aB?\"f6  
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： d%#!nq{vd  
enableservice('AutomationServer', true) "'z,[v50&  
enableservice('AutomationServer') Sc4obcw%  
.)"_Q/q  
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。

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： Ge^zX$.'  
1. 在FRED脚本编辑界面找到参考. )h>\05|T  
2. 找到Matlab Automation Server Type Library 7K>D@O  
3. 将名字改为MLAPP QQg8+{>

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。 vU_d=T%$

现在将脚本代码公布如下，此脚本执行如下几个步骤： ]6$,IKE7  
1. 创建Matlab服务器。 j4~7akG  
2. 移动探测面对于前一聚焦面的位置。 8)^B32  
3. 在探测面追迹光线 w(76H^e  
4. 在探测面计算照度 Q00R<hu@F  
5. 使用PutWorkspaceData发送照度数据到Matlab Jv_.itc  
6. 使用PutFullMatrix发送标量场数据到Matlab中 _ztZ>'  
7. 用Matlab画出照度数据 csH2_+uG  
8. 在Matlab计算照度平均值 FAQr~G}  
9. 返回数据到FRED中 hpbwZ
