[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。 J Jy{@[m  
"$8w.C  
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 z%tA39m  
enableservice('AutomationServer', true) oh\1>3,Ns  
enableservice('AutomationServer') B||c(ue  
x!?Z*v@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。 sXB+s
  
I:t^S.,  
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： ;r!\-]5$  
1. 在FRED脚本编辑界面找到参考. w3bIb$12  
2. 找到Matlab Automation Server Type Library [g|Hj)(  
3. 将名字改为MLAPP l0`'5>

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。 s.y}U5Ty?P

现在将脚本代码公布如下，此脚本执行如下几个步骤： S=O$JP79  
1. 创建Matlab服务器。 wLMvC{5  
2. 移动探测面对于前一聚焦面的位置。 $L&BT 0  
3. 在探测面追迹光线 f)^t')  
4. 在探测面计算照度 0N VI+Z$  
5. 使用PutWorkspaceData发送照度数据到Matlab U**)H_S/~  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Z| L2oce  
7. 用Matlab画出照度数据 e\.HWV]I  
8. 在Matlab计算照度平均值 F< |c4  
9. 返回数据到FRED中 R3G@G
