    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。 ~~Ezt*lH  
    ;ryNfP%  
    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: @ 2)nhW/z6  
    enableservice('AutomationServer', true) 2_+>a"8Y  
    enableservice('AutomationServer') PD-&(ka.  
    }|Mwv $`  
    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 -` U |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: 9ziFjP+1  
    1. 在FRED脚本编辑界面找到参考. /uj^w&l#  
    2. 找到Matlab Automation Server Type Library ]f0'YLG  
    3. 将名字改为MLAPP E)gD"^rex  
    !}#> ky!t  
    f 7lj,GAZ  
    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。 _>R aw

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -}|L<~  
    1. 创建Matlab服务器。 uK2HtRY1  
    2. 移动探测面对于前一聚焦面的位置。 1 _?8OU  
    3. 在探测面追迹光线 iM)K:L7d  
    4. 在探测面计算照度 SG&,o =I$  
    5. 使用PutWorkspaceData发送照度数据到Matlab ApXf<MAy  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 v$|~ g'6  
    7. 用Matlab画出照度数据 ~Ld5WEp k3  
    8. 在Matlab计算照度平均值 ^{4BcM7eH  
    9. 返回数据到FRED中 yx :^*/
