    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。 NId.TaXh  
    xLOQu.  
    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: xSK#ovH2  
    enableservice('AutomationServer', true) Kob,}NgqZ  
        enableservice('AutomationServer') mOn_#2=KF  
    *pS 7,Hm  
    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 \'*M }G  
    VK1B}5/  
    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: TSsZzsdr2  
    1. 在FRED脚本编辑界面找到参考. [{BY$"b#:  
    2. 找到Matlab Automation Server Type Library SFDTHvXu#_  
        3. 将名字改为MLAPP {o)pwM"@(  
         Q^rR}Ws  
         Y`bTf@EP>  
    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。 rHX^bcYK

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %g.cE}^  
    1. 创建Matlab服务器。 AO|9H`6U6F  
    2. 移动探测面对于前一聚焦面的位置。 4<F z![>  
    3. 在探测面追迹光线 tMiIlf!>p  
    4. 在探测面计算照度 ^Q$OzsEk  
    5. 使用PutWorkspaceData发送照度数据到Matlab c!4F0(n4  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 4r1\&sI$~  
    7. 用Matlab画出照度数据 GN(<$,~g  
    8. 在Matlab计算照度平均值 `9J9[!+!`  
    9. 返回数据到FRED中 r%ES#\L6+|
