FRED案例-FRED如何调用Matlab

N9pwWg&<+  
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。 sqT^t!  
R+s1[Z  
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: A$Wx#r7)  
enableservice('AutomationServer', true) ~,T+JX  
    enableservice('AutomationServer') q=njKC  
+miR3~w.  
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。 gd K*"U  
M</Wd{.g"  
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: ><X $#  
1. 在FRED脚本编辑界面找到参考. |Hfl&3  
2. 找到Matlab Automation Server Type Library !\ZcOk2  
    3. 将名字改为MLAPP ;t|,nz4kJ  
     5.dl>,  
     _@~PL>g"p  
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。 cg{Gc]'1#

现在将脚本代码公布如下,此脚本执行如下几个步骤: 9Yn)t#G'`F  
1. 创建Matlab服务器。 } #qQ2NCH  
2. 移动探测面对于前一聚焦面的位置。 LaclC]yLU  
3. 在探测面追迹光线 2Q}7fht  
4. 在探测面计算照度 L $SMfx  
5. 使用PutWorkspaceData发送照度数据到Matlab AxEc^Cof  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {gw [%[ZM  
7. 用Matlab画出照度数据 ?]5Ix1  
8. 在Matlab计算照度平均值 `4skwvS=  
9. 返回数据到FRED中 hox< vr4
