[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。 lQ5d.}O&  
~bC-0^/ 8|  
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： 8s+9PE  
enableservice('AutomationServer', true) YCMXF#1  
enableservice('AutomationServer') ^~dBO%M^  
Mk=
M)d`  
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。 (3. B\8s

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： ML:Zm~A1U  
1. 在FRED脚本编辑界面找到参考. 5f#N$mh  
2. 找到Matlab Automation Server Type Library /J@<e{&t~  
3. 将名字改为MLAPP .{\lbI

As}3VBd  
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。 /-FvC^Fj

现在将脚本代码公布如下，此脚本执行如下几个步骤： [{&GMc   
1. 创建Matlab服务器。 Q

2. 移动探测面对于前一聚焦面的位置。 $V/Hr/0  
3. 在探测面追迹光线 e9\eh? bPU  
4. 在探测面计算照度 EOj.Jrs~  
5. 使用PutWorkspaceData发送照度数据到Matlab ;xXD2{q  
6. 使用PutFullMatrix发送标量场数据到Matlab中 UR{OrNg*  
7. 用Matlab画出照度数据 _n~[wb5J  
8. 在Matlab计算照度平均值 2%{(BT6  
9. 返回数据到FRED中 D*_Z"q_B
