    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。 ,PKUgL}w  
    0oi.k;  
    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: tdu:imH~  
    enableservice('AutomationServer', true) }+u<w{-7/  
        enableservice('AutomationServer') [;D1O;c'W.  
    5yV>-XT+-  
    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 C\bJ_vl;'  
    4@ny%_/  
    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: [V;u7Z\r-  
    1. 在FRED脚本编辑界面找到参考. $ Grk{]nT  
    2. 找到Matlab Automation Server Type Library qI74a F  
        3. 将名字改为MLAPP `!ja0Sq]U  
         2*n~r  
         K^b'<} $|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。 8yZs>Og?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %(\et%[]  
    1. 创建Matlab服务器。 'XYjo&w  
    2. 移动探测面对于前一聚焦面的位置。 pd.pY*B<[  
    3. 在探测面追迹光线 H:z<]Rc  
    4. 在探测面计算照度 ?4W6TSW-'  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2G:KaQ)  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 c,G[Rk  
    7. 用Matlab画出照度数据 YXU2UIY<~  
    8. 在Matlab计算照度平均值 Y31e1   
    9. 返回数据到FRED中 ,n>K$
