FRED案例-FRED如何调用Matlab

Db"DG(  
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。 U=8@@ yE  
v_<2H' *Q  
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: )f dE6  
enableservice('AutomationServer', true) Qo =Kqv  
    enableservice('AutomationServer') "g+z !4b#  
FecktD=  
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。 ^h &I H|

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: |Oag,o"  
1. 在FRED脚本编辑界面找到参考. Dr;iQkGP  
2. 找到Matlab Automation Server Type Library xmGk*W)P  
    3. 将名字改为MLAPP h O emt  
     E| :!Q8"%w  
     ZX~ _g@  
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。 US{3pkr;I]

现在将脚本代码公布如下,此脚本执行如下几个步骤: 2l5KJlfj>k  
1. 创建Matlab服务器。 [Vdz^_@Y  
2. 移动探测面对于前一聚焦面的位置。 h8jD }9^  
3. 在探测面追迹光线 *V(Fn-6(  
4. 在探测面计算照度 j8 C8X$  
5. 使用PutWorkspaceData发送照度数据到Matlab (cv!Y=]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 yg]2erR  
7. 用Matlab画出照度数据 s=Q(C[%I  
8. 在Matlab计算照度平均值 E2B>b[  
9. 返回数据到FRED中 @/%{15s.
