[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。 .[o`TlG%  
wRJ`RKJ-T  
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： 8aI^vP"7`=  
enableservice('AutomationServer', true) -H$C3V3]  
enableservice('AutomationServer') B<jVo%og  
f\~A72-  
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。 <[V1z=Eo/]

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： f`-UC_(;  
1. 在FRED脚本编辑界面找到参考. c\VD8 :  
2. 找到Matlab Automation Server Type Library  k<  
3. 将名字改为MLAPP 2Zr,@LC

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。 R_Uy.0=4

现在将脚本代码公布如下，此脚本执行如下几个步骤： *mkL>v &  
1. 创建Matlab服务器。 -EG=}uT['b  
2. 移动探测面对于前一聚焦面的位置。 !BN@cc[%  
3. 在探测面追迹光线 z0?IQzR^T  
4. 在探测面计算照度 `vD.5  
5. 使用PutWorkspaceData发送照度数据到Matlab QW2SFpE  
6. 使用PutFullMatrix发送标量场数据到Matlab中 '6GW.;  
7. 用Matlab画出照度数据 v8>bR|n5  
8. 在Matlab计算照度平均值 2I{kLN1TY  
9. 返回数据到FRED中 '1b4nj|<m
