    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。 i"j(b|?e  
    /LM4- S  
    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: &l?+3$q  
    enableservice('AutomationServer', true) vw)7 !/#  
        enableservice('AutomationServer') :SsUdIX;P  
    KHDZ  
    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 er.CDKD%L

    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: l6u&5[C  
    1. 在FRED脚本编辑界面找到参考. HSIvWhg?p  
    2. 找到Matlab Automation Server Type Library _7D_72  
        3. 将名字改为MLAPP Do]*JO)(  
         cM_ Fp  
         bhs(Qzx  
    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。 aRc'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =q"eU=9  
    1. 创建Matlab服务器。 c:l]=O   
    2. 移动探测面对于前一聚焦面的位置。 2Nj9U#A  
    3. 在探测面追迹光线 SxjCwX">  
    4. 在探测面计算照度 ~=Ncp9ej#  
    5. 使用PutWorkspaceData发送照度数据到Matlab !%Y~~'5 h  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 @wq#>bm  
    7. 用Matlab画出照度数据 ?'r9"M>  
    8. 在Matlab计算照度平均值 ?Mp1~{8  
    9. 返回数据到FRED中 ^<0IB#dA
