[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。 yKC1h`2

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： +77B656  
enableservice('AutomationServer', true) !iW>xo  
enableservice('AutomationServer') sAoxLI  
mTLJajE/  
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。 @iN"]GFjS

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： 8"o@$;C  
1. 在FRED脚本编辑界面找到参考. plM:7#eA  
2. 找到Matlab Automation Server Type Library +9B .}t#  
3. 将名字改为MLAPP cVDcda|PE

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。 &mm!UJ

现在将脚本代码公布如下，此脚本执行如下几个步骤： 1o?uf,H7O  
1. 创建Matlab服务器。 "6Z(0 iu:{  
2. 移动探测面对于前一聚焦面的位置。 E@4/<;eKK  
3. 在探测面追迹光线 z#2n+hwE  
4. 在探测面计算照度 9T0g%&  
5. 使用PutWorkspaceData发送照度数据到Matlab \r"gqv)^  
6. 使用PutFullMatrix发送标量场数据到Matlab中 zpZfsn!  
7. 用Matlab画出照度数据 %a!gN  
8. 在Matlab计算照度平均值 G"h}6Za;DO  
9. 返回数据到FRED中 ygQe'S{!S\
