[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。 ?DAW~+,!7o  
?J;*  
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： Dv7/eRt  
enableservice('AutomationServer', true) gq$]jWtCD  
enableservice('AutomationServer') c|f)k:Q  
1|4'3^3  
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。 8J&K_JC^

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： x]({Po4  
1. 在FRED脚本编辑界面找到参考. c$<7&{Pb  
2. 找到Matlab Automation Server Type Library @J[l^o9  
3. 将名字改为MLAPP 6bL"ZOEu

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。 aLwd#/!

1. 创建Matlab服务器。 Z19d Ted33  
2. 移动探测面对于前一聚焦面的位置。 }m?1IU%q  
3. 在探测面追迹光线 hFC4CqBV  
4. 在探测面计算照度 w|6;Pf~1y)  
5. 使用PutWorkspaceData发送照度数据到Matlab _$OhV#LKG  
6. 使用PutFullMatrix发送标量场数据到Matlab中 91oIxW  
7. 用Matlab画出照度数据 'o2V}L'nG  
8. 在Matlab计算照度平均值 G\ twx ;  
9. 返回数据到FRED中 ;pU#3e+P8
