[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。 12lX-~[["  
2yK">xYY@  
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： ULAr!  
enableservice('AutomationServer', true) bqED5;d'#  
enableservice('AutomationServer') Ef#LRcG-Z  
Nhs!_-_I  
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。

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： hiS|&5#  
1. 在FRED脚本编辑界面找到参考. H<Sf0>OA  
2. 找到Matlab Automation Server Type Library dO82T3T  
3. 将名字改为MLAPP Z8v8@Y

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。 a%r!55.

现在将脚本代码公布如下，此脚本执行如下几个步骤： +b-ON@9]J`  
1. 创建Matlab服务器。 w~u{"E$  
2. 移动探测面对于前一聚焦面的位置。 R->x_9y-

3. 在探测面追迹光线 `xzKRId0  
4. 在探测面计算照度 Qx4)'
n  
5. 使用PutWorkspaceData发送照度数据到Matlab ,m<YSMKX  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~^obf(N`  
7. 用Matlab画出照度数据 _<c"/B  
8. 在Matlab计算照度平均值 (%fQhQ  
9. 返回数据到FRED中 ~Y/A]N86,
