    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。 9rr"q5[  
    QGtKu:c.81  
    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: \:cr2w'c  
    enableservice('AutomationServer', true) tL?nO#Qx  
    enableservice('AutomationServer') r-#23iT.~  
    mK3U*)A   
    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 7l"N%e  
    Cd:ofv/3  
    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: H7 acT  
    1. 在FRED脚本编辑界面找到参考. V9:h4]  
    2. 找到Matlab Automation Server Type Library \;w+_<zE5{  
    3. 将名字改为MLAPP hadGF%> O6  
    'Ldlo+*|5

    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。 hjB G`S#

    o(iN}.c  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: w$~|/UrLf  
    1. 创建Matlab服务器。 t'@1FA!)  
    2. 移动探测面对于前一聚焦面的位置。 0ad -4  
    3. 在探测面追迹光线 S0V%JY;Gv  
    4. 在探测面计算照度 =]h5RC  
    5. 使用PutWorkspaceData发送照度数据到Matlab y6|&bJ @  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )NeI]p  
    7. 用Matlab画出照度数据 @Oe!*|?mS  
    8. 在Matlab计算照度平均值 JO:40V?op  
    9. 返回数据到FRED中 OO.. Y
