FRED如何调用Matlab

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。 N6[Z*5efR  
e)H FI|>  
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: `lY-/Ty  
enableservice('AutomationServer', true) @g[ijs\  
enableservice('AutomationServer') aUMiRm-   
(h wzA *(c  
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。 vVBWhY]  
c^_+<C-F  
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: $~8gh>`]  
1. 在FRED脚本编辑界面找到参考. SVa^:\"$[  
2. 找到Matlab Automation Server Type Library 2po8n _  
3. 将名字改为MLAPP qg j;E=7  
Oyb9 ql^  
Lj /^cx  
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。 -d?<t}a

现在将脚本代码公布如下,此脚本执行如下几个步骤: bSTori5  
1. 创建Matlab服务器。 F4=X(P_6  
2. 移动探测面对于前一聚焦面的位置。 */{y%  
3. 在探测面追迹光线 HA c"&#pG  
4. 在探测面计算照度 |+h x2?Nv  
5. 使用PutWorkspaceData发送照度数据到Matlab VKPsg  
6. 使用PutFullMatrix发送标量场数据到Matlab中 <e Y2}Ml  
7. 用Matlab画出照度数据 }Q[U4G  
8. 在Matlab计算照度平均值 k Jz^\Re  
9. 返回数据到FRED中 vmxS^_I
