[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。 t"J{qfNs

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：
,(sE|B#s  
enableservice('AutomationServer', true) \4<|QE  
enableservice('AutomationServer') Ets6tM`  
]8$H'u(C  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 {0/2Hw n  
/yx)_x{  
在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： Nq9M$Nt]  
1. 在FRED脚本编辑界面找到参考.  ZpBP#Y*  
2. 找到Matlab Automation Server Type Library *D[yA  
3. 将名字改为MLAPP ^liW*F"UY

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。 lS p"(&

现在将脚本代码公布如下，此脚本执行如下几个步骤： BjTgZ98J  
1. 创建Matlab服务器。 JwWxM3(%t  
2. 移动探测面对于前一聚焦面的位置。 6<5:m:KE  
3. 在探测面追迹光线 v7#|%  
4. 在探测面计算照度 &?xmu204  
5. 使用PutWorkspaceData发送照度数据到Matlab Gp)J[8j  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ?0JNaf  
7. 用Matlab画出照度数据 x`IWo:j  
8. 在Matlab计算照度平均值 }ksp(.}G  
9. 返回数据到FRED中 *0V'rH)
