FRED案例-FRED如何调用Matlab

Z^Wv(:Nr  
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。 EP90E^v^  
a[,p1}!_  
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: VV#'d  
enableservice('AutomationServer', true) I.>8p]X  
    enableservice('AutomationServer') 1(_[awBx  
DwK$c^2q{.  
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。 **oDQwW]*  
Q'hs,t1<  
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: sO!m,pK(  
1. 在FRED脚本编辑界面找到参考. * bhb=~  
2. 找到Matlab Automation Server Type Library (dy:d^  
    3. 将名字改为MLAPP 7VdxQ T  
     G8MLg#  
     qP zxP @4  
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。 T-iQ!D~

现在将脚本代码公布如下,此脚本执行如下几个步骤: #;+SAoN  
1. 创建Matlab服务器。 -G'3&L4 D  
2. 移动探测面对于前一聚焦面的位置。 -i_XP]b&  
3. 在探测面追迹光线 kw7E<aF!  
4. 在探测面计算照度 &m]jYvRc  
5. 使用PutWorkspaceData发送照度数据到Matlab V&/Cb&~Uw  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .$Yp~  
7. 用Matlab画出照度数据 I47sqz7  
8. 在Matlab计算照度平均值 ytb1hFs  
9. 返回数据到FRED中 9+8N-LZ
