[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。 ~w"e 2a  
RKD$'UWX  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令：
\VHRI<$+5  
enableservice('AutomationServer', true) Hd?#^X  
enableservice('AutomationServer') Mc/= Fs  
ewVks>lbz  
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。 ~%QI#s?|

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： Eu`K2_

1. 在FRED脚本编辑界面找到参考. O[15xH,  
2. 找到Matlab Automation Server Type Library v{oHC4  
3. 将名字改为MLAPP !m6=Us  
ASULg{  
sPRo=LB  
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。 DH!_UV

现在将脚本代码公布如下，此脚本执行如下几个步骤： wPl9%  
1. 创建Matlab服务器。 As>P(  
2. 移动探测面对于前一聚焦面的位置。 Nbd[xs-lw  
3. 在探测面追迹光线 8B7~Nq'  
4. 在探测面计算照度 DTz)qHd#X  
5. 使用PutWorkspaceData发送照度数据到Matlab =&#t("  
6. 使用PutFullMatrix发送标量场数据到Matlab中 |SuN3B4e  
7. 用Matlab画出照度数据 9@wmngvM*Y  
8. 在Matlab计算照度平均值 #r'S@:[  
9. 返回数据到FRED中 `@^s}rt+
