[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。 "2'4b  
Y["aw&;#O\  
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： 0+3_CS++r  
enableservice('AutomationServer', true) fl@=h[g#t  
enableservice('AutomationServer') }^Ymg
7wA  
p9X{E%A<:  
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。 7l%]O}!d)

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： ;r8< Ed
  
1. 在FRED脚本编辑界面找到参考. t_xO-fT)  
2. 找到Matlab Automation Server Type Library ^+J3E4  
3. 将名字改为MLAPP *C~$<VYI

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。 qX9x#92

现在将脚本代码公布如下，此脚本执行如下几个步骤： ;9&#Sb/  
1. 创建Matlab服务器。 `/"*_AKAI  
2. 移动探测面对于前一聚焦面的位置。 n=F|bW  
3. 在探测面追迹光线 xcHuH-}  
4. 在探测面计算照度 BT*z^ZH  
5. 使用PutWorkspaceData发送照度数据到Matlab 6lAHB*`  
6. 使用PutFullMatrix发送标量场数据到Matlab中 cM?i _m  
7. 用Matlab画出照度数据 Z>l%:;H  
8. 在Matlab计算照度平均值 D[H #W[  
9. 返回数据到FRED中 N+N98~Y`P
