    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。 G;G*!nlWf  
    G&g;ROgY  
    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: kg7F8($  
    enableservice('AutomationServer', true) /:4J  
    enableservice('AutomationServer') )/$J$'mcxd  
    c,~uurVi  
    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 3U@jw,K!{A  
    )[Tm[o?Y.  
    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: 2X@9o4_4q  
    1. 在FRED脚本编辑界面找到参考. #Q8_:dPY  
    2. 找到Matlab Automation Server Type Library ?Ij(B}D  
    3. 将名字改为MLAPP f CU]

    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。 +; KUL6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ,<Q  
    1. 创建Matlab服务器。 HoGYgye=  
    2. 移动探测面对于前一聚焦面的位置。 ,>a!CnK=  
    3. 在探测面追迹光线 loVg{N :  
    4. 在探测面计算照度 wXQxZuk[  
    5. 使用PutWorkspaceData发送照度数据到Matlab kK[4uQQ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 N#T'}>ty  
    7. 用Matlab画出照度数据 J\@6YU[A  
    8. 在Matlab计算照度平均值 Ou_H&R  
    9. 返回数据到FRED中 ^1S{::
