[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。 E:(flW=  
`pE~M05  
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： f$NudG!S  
enableservice('AutomationServer', true) 1-1x,U7w  
enableservice('AutomationServer') &n6mXFF#>P  
Y
tc  
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。 P8Fq %k  
y|nMCkuX  
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： I7nt<l!  
1. 在FRED脚本编辑界面找到参考. UBrYN'QRNt  
2. 找到Matlab Automation Server Type Library B[
!wo  
3. 将名字改为MLAPP ^LE`Y>&m

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。 I`}-*%ki(

现在将脚本代码公布如下，此脚本执行如下几个步骤： B8'" ^a^&-  
1. 创建Matlab服务器。 ce/Rzid  
2. 移动探测面对于前一聚焦面的位置。 Lf&p2p?~c  
3. 在探测面追迹光线 vX]\Jqy  
4. 在探测面计算照度 V{O,O,*  
5. 使用PutWorkspaceData发送照度数据到Matlab `ux U H#  
6. 使用PutFullMatrix发送标量场数据到Matlab中 bg*4Z?[dd  
7. 用Matlab画出照度数据 3205gI,  
8. 在Matlab计算照度平均值 |rka/_  
9. 返回数据到FRED中 5. 5
