    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。 l_$>$d  
    <#;5)!gr{  
    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: F|y0q:U  
    enableservice('AutomationServer', true) B0A y  
    enableservice('AutomationServer') fAz4>_4  
    E.sZjo1  
    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 );y ZyWDV  
    `sIm&.d  
    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: \x:U`T  
    1. 在FRED脚本编辑界面找到参考. Iw`|,-|  
    2. 找到Matlab Automation Server Type Library B u%%O8  
    3. 将名字改为MLAPP +'iqGg-  
    xLLTp7b(  
     qT #=C'?  
    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。 ?Q+*[YEJ5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: `QRXQ c  
    1. 创建Matlab服务器。 n[r1h=?j3  
    2. 移动探测面对于前一聚焦面的位置。 _V e)M%  
    3. 在探测面追迹光线 Gd`7Tf)'  
    4. 在探测面计算照度 SK&1l`3  
    5. 使用PutWorkspaceData发送照度数据到Matlab S 1^t;{"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @8w5Oudvx  
    7. 用Matlab画出照度数据 V2AsZc0U(  
    8. 在Matlab计算照度平均值 __s'/ 6u  
    9. 返回数据到FRED中 Rq e|7/As
