[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。 *3(mNpi{_  
:f0#4'f  
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."d\  
enableservice('AutomationServer', true) 
nz/cs n  
enableservice('AutomationServer') G9~ 4?v6:  
Yo}QW;,g  
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。 &iaS3x

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： -=2V4WU~  
1. 在FRED脚本编辑界面找到参考. V17!~  
2. 找到Matlab Automation Server Type Library ]9}^}U1."  
3. 将名字改为MLAPP $OaxetPH

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。 j;EH[3

现在将脚本代码公布如下，此脚本执行如下几个步骤： 6P02=  
1. 创建Matlab服务器。 1P G"IaOb  
2. 移动探测面对于前一聚焦面的位置。 WIw*//nw  
3. 在探测面追迹光线  ^]?juL  
4. 在探测面计算照度 3]pHc)p!.  
5. 使用PutWorkspaceData发送照度数据到Matlab D/Py?<n-B  
6. 使用PutFullMatrix发送标量场数据到Matlab中 r"`7ezun:  
7. 用Matlab画出照度数据 n]jw!;  
8. 在Matlab计算照度平均值 e. R9:  
9. 返回数据到FRED中 sE[ Yg8yAt
