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。 JAlU%n?R  
Re*|$r#  
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: ' :\fl.b  
enableservice('AutomationServer', true) <Zp^lDxa  
enableservice('AutomationServer') L6:W'u^  
q]6_ rY.  
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。 X*sr

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: |1(rr%  
1. 在FRED脚本编辑界面找到参考. =n-z;/NL  
2. 找到Matlab Automation Server Type Library l#D-q/k?  
3. 将名字改为MLAPP I?a8h`WS+  
"v(G7*2

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。 &P 8!]:

现在将脚本代码公布如下,此脚本执行如下几个步骤: V43nws "4  
1. 创建Matlab服务器。 ! FNf>z+  
2. 移动探测面对于前一聚焦面的位置。 GS\%mPZ  
3. 在探测面追迹光线 'nRp}s1^[  
4. 在探测面计算照度 [E>R.Oe  
5. 使用PutWorkspaceData发送照度数据到Matlab -uWKY6 :5  
6. 使用PutFullMatrix发送标量场数据到Matlab中 cYGRy,'gH  
7. 用Matlab画出照度数据 8HMo.*Ti9  
8. 在Matlab计算照度平均值 N-[n\}'  
9. 返回数据到FRED中 -$U@By<SJ
