[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。 SV7;B?e%Y  
m/HT3<F  
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： sdp&D@  
enableservice('AutomationServer', true) ,Oo`*'a[o7  
enableservice('AutomationServer') I-#H+\S  
ts]e M1;  
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。 z^Hc'oVXj:  
\#sD`O  
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： 2"/MM2s  
1. 在FRED脚本编辑界面找到参考. 1gI7$y+?  
2. 找到Matlab Automation Server Type Library GgO5

3. 将名字改为MLAPP 3?OQ-7,

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。 q'3{M]Tk

现在将脚本代码公布如下，此脚本执行如下几个步骤： a~o<>H  
1. 创建Matlab服务器。 K#"=*p,  
2. 移动探测面对于前一聚焦面的位置。 VRo&1:  
3. 在探测面追迹光线 y\Wn:RR1[  
4. 在探测面计算照度 +qi& ?}  
5. 使用PutWorkspaceData发送照度数据到Matlab 62xOh\(  
6. 使用PutFullMatrix发送标量场数据到Matlab中 kk4 |4  
7. 用Matlab画出照度数据 ucCf%T\:  
8. 在Matlab计算照度平均值 t}t(fJHY`  
9. 返回数据到FRED中 !j~wAdHk
