    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。 %+=y!  
    pr;z>|FgA>  
    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: m#^ua^JV  
    enableservice('AutomationServer', true) 2%|0c\y|z=  
        enableservice('AutomationServer') HVq02 Z  
    ) Ekd  
    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 g ss 3e&

    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: uVQH,NA,  
    1. 在FRED脚本编辑界面找到参考. 9}=]oX!+V  
    2. 找到Matlab Automation Server Type Library (iT?uMRz  
        3. 将名字改为MLAPP =`1#fQDt

         !ULU#2'1  
    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。 0|D^_1W`R

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Tx+Bkfj  
    1. 创建Matlab服务器。 w,,QXJe{Z_  
    2. 移动探测面对于前一聚焦面的位置。 b,k%n_&n  
    3. 在探测面追迹光线 2$fFl,v!z  
    4. 在探测面计算照度 =Fd!wkB'{  
    5. 使用PutWorkspaceData发送照度数据到Matlab 4Z& i\#Q  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 iK(G t6w  
    7. 用Matlab画出照度数据 g}vOp3 ^  
    8. 在Matlab计算照度平均值 oC~8h8"l  
    9. 返回数据到FRED中 MKnG:)T<?l
