    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。 78-:hk  
    XN;eehB?aE  
    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: s_TM!LRUcw  
    enableservice('AutomationServer', true) ) b8*>k  
        enableservice('AutomationServer') W=m_G]"L  
    y;jyfc$ `  
    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 8<xy *=%  
    $u sU  
    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: *1n:  
    1. 在FRED脚本编辑界面找到参考. ! N p  
    2. 找到Matlab Automation Server Type Library L)5nb-qp  
        3. 将名字改为MLAPP ~^*tIIOX  
         O 7sn>uO  
         j@2 hI,+  
    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=9H*e

    现在将脚本代码公布如下,此脚本执行如下几个步骤: OA0\b_  
    1. 创建Matlab服务器。 DI7trR`  
    2. 移动探测面对于前一聚焦面的位置。 ceCshxTU  
    3. 在探测面追迹光线 $7,dKC &  
    4. 在探测面计算照度 0^4*[?l9q  
    5. 使用PutWorkspaceData发送照度数据到Matlab oSoG&4  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 TxWj gW~  
    7. 用Matlab画出照度数据 n'H\*9t  
    8. 在Matlab计算照度平均值 I"1\R8 R  
    9. 返回数据到FRED中 T Bco
