[分享]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。 IS5.i95m  
uMiD*6,$<  
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： +
SZ%&  
enableservice('AutomationServer', true) {UV<=R,E  
enableservice('AutomationServer') PMz{8 F  
XudH
 
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。 ZTgAZ5_cz

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： 1`2);b{@  
1. 在FRED脚本编辑界面找到参考. *<|~=*Ddf  
2. 找到Matlab Automation Server Type Library '0])7jq  
3. 将名字改为MLAPP q>D4m

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。 1{\,5U&

现在将脚本代码公布如下，此脚本执行如下几个步骤： d @^o/w8  
1. 创建Matlab服务器。  9

2. 移动探测面对于前一聚焦面的位置。 `ohF?5J,  
3. 在探测面追迹光线 G]m[S-  
4. 在探测面计算照度 ^cPo{xf  
5. 使用PutWorkspaceData发送照度数据到Matlab u$Pf.#  
6. 使用PutFullMatrix发送标量场数据到Matlab中 i SAidK

7. 用Matlab画出照度数据 l7D4`i<F  
8. 在Matlab计算照度平均值 VAF:Z  
9. 返回数据到FRED中 Un8#f+odR
