    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。 f\);HJbg  
    Yuo1'gE+  
    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: CQjZAv  
    enableservice('AutomationServer', true) :{b6M/  
        enableservice('AutomationServer') Sci4EGc  
    gO:Z6}3vM  
    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 6~F#F)C'

    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: ,3]?%t0xe  
    1. 在FRED脚本编辑界面找到参考. C8qTz".5$  
    2. 找到Matlab Automation Server Type Library mKq<'t]^k  
        3. 将名字改为MLAPP xw+<p  
         KT];SF ^Y  
         mvTyx7 h=  
    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。 ri<'-wi

    现在将脚本代码公布如下,此脚本执行如下几个步骤: oB0 8  
    1. 创建Matlab服务器。 !jAWNK6  
    2. 移动探测面对于前一聚焦面的位置。 P 0Efh?oZ  
    3. 在探测面追迹光线 x'2 ,sE  
    4. 在探测面计算照度 D#d8^U  
    5. 使用PutWorkspaceData发送照度数据到Matlab nEd M_JPv  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 P#[IUXtT  
    7. 用Matlab画出照度数据 V Z2.w4b  
    8. 在Matlab计算照度平均值 +2EHmuJ;  
    9. 返回数据到FRED中 : _^0'ULP
