[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。 d*l2x[8}g-  
C'a#.LM  
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： C;']FmK]  
enableservice('AutomationServer', true) V:2{LR<R8  
enableservice('AutomationServer') K$5mDScoJ  
"6>+IF  
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。 :Q"p!,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： uVa`2]NV r  
1. 在FRED脚本编辑界面找到参考. JwdvY]  
2. 找到Matlab Automation Server Type Library 6)_h'v<|M  
3. 将名字改为MLAPP 64t:  
a$$aM2.2  
w6|l ~.$=  
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。 4c@_u

现在将脚本代码公布如下，此脚本执行如下几个步骤： R[}fr36>/  
1. 创建Matlab服务器。 G x{G}9  
2. 移动探测面对于前一聚焦面的位置。 6\xfoy|j  
3. 在探测面追迹光线 OXF/4Oe  
4. 在探测面计算照度 t]8nRZ1  
5. 使用PutWorkspaceData发送照度数据到Matlab ~{l @
  
6. 使用PutFullMatrix发送标量场数据到Matlab中

7. 用Matlab画出照度数据 =" pNE#  
8. 在Matlab计算照度平均值  BF /4  
9. 返回数据到FRED中 )3)x/WM
