    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。 }P=FMme{F(  
    *3^7'^j<  
    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: EQnU:a  
    enableservice('AutomationServer', true) FoIK, MdJ  
    enableservice('AutomationServer') `?:{aOI  
    w2$ L;q  
    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 r:xg#&"*  
    @"cnPLh&  
    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: 1`II%mf[  
    1. 在FRED脚本编辑界面找到参考. zt((TD2  
    2. 找到Matlab Automation Server Type Library mj9|q8v{+  
    3. 将名字改为MLAPP 4o''C |ND

    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。 @#"K6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1>_$O|dE  
    1. 创建Matlab服务器。 r?`nc6$0|  
    2. 移动探测面对于前一聚焦面的位置。 E=v4|/['N  
    3. 在探测面追迹光线 `,  |l  
    4. 在探测面计算照度 uA?a DjA  
    5. 使用PutWorkspaceData发送照度数据到Matlab \#h=pz+jb  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 CE183l\  
    7. 用Matlab画出照度数据 _ru<1n[4~  
    8. 在Matlab计算照度平均值 4P2p|Gc3  
    9. 返回数据到FRED中 84(jg P
