[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。 rQGInzYp  
1?^ P=^8   
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： je2"D7D  
enableservice('AutomationServer', true) &A.0(s  
enableservice('AutomationServer') 9-q> W  
QV HI}3~  
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>i<2  
,}@4@ >?K  
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： !OQ5AF$  
1. 在FRED脚本编辑界面找到参考. !G\gqkSL  
2. 找到Matlab Automation Server Type Library %72(gR2Wa2  
3. 将名字改为MLAPP @#hvQ6u

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。 ^b`-zFL7

现在将脚本代码公布如下，此脚本执行如下几个步骤： ILl~f\xG)  
1. 创建Matlab服务器。 ~|Ln9f-g  
2. 移动探测面对于前一聚焦面的位置。 _[rQt8zn  
3. 在探测面追迹光线 (3D&GY!/  
4. 在探测面计算照度 PN8#T:E  
5. 使用PutWorkspaceData发送照度数据到Matlab .K(9=yh  
6. 使用PutFullMatrix发送标量场数据到Matlab中 H~vrCi~t"  
7. 用Matlab画出照度数据 <;W-!R759  
8. 在Matlab计算照度平均值 u kZK*Y9P  
9. 返回数据到FRED中 |4 \2,M
