[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。 A}3=561F?5  
rV T{90,  
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：  ~Hr}]  
enableservice('AutomationServer', true) -De9_0#R  
enableservice('AutomationServer') UOxkO  
''0fF_P  
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。 [E/\#4b

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： osX8eX]\  
1. 在FRED脚本编辑界面找到参考. Y07ZB'K  
2. 找到Matlab Automation Server Type Library GJoS#s  
3. 将名字改为MLAPP "HDcmIXg&

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。 @NNq z

现在将脚本代码公布如下，此脚本执行如下几个步骤： `s8{C b=}1  
1. 创建Matlab服务器。 N<IT w/@^  
2. 移动探测面对于前一聚焦面的位置。 {z")7g ]l  
3. 在探测面追迹光线 fR*q?,  
4. 在探测面计算照度 ]]oI#*c  
5. 使用PutWorkspaceData发送照度数据到Matlab Vv.|br`;}  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ,v';>.]  
7. 用Matlab画出照度数据 tX> G,hw  
8. 在Matlab计算照度平均值 IHcD*zQ  
9. 返回数据到FRED中 &3TEfvz
