[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。 c:

Kp?):6  
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： H59}d oKH  
enableservice('AutomationServer', true) -1).'aJ^  
enableservice('AutomationServer') y<mmv~=  
9bvzt8pc  
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。 e! V`cg0

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： y1R53u`;L  
1. 在FRED脚本编辑界面找到参考. qN((Xz+AZE  
2. 找到Matlab Automation Server Type Library 3wZA,Z  
3. 将名字改为MLAPP n'R9SnW

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。 7U68|\fI!

现在将脚本代码公布如下，此脚本执行如下几个步骤： c{4C4'GD  
1. 创建Matlab服务器。 :*

2. 移动探测面对于前一聚焦面的位置。 lZoy(kdc  
3. 在探测面追迹光线 ;=\vm"I?  
4. 在探测面计算照度 @IL_  
5. 使用PutWorkspaceData发送照度数据到Matlab R2{y1b$l  
6. 使用PutFullMatrix发送标量场数据到Matlab中 q\wT[W31@  
7. 用Matlab画出照度数据 EIZSV>  
8. 在Matlab计算照度平均值 q#9JJWSs  
9. 返回数据到FRED中 %oVoE2T{@
