    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。 Nq[uoaT  
    KIf dafRL  
    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: w^|*m/h|@u  
    enableservice('AutomationServer', true) ?k&Vy  
    enableservice('AutomationServer') cWsNr'MS*  
    mbxZL<ua  
    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 \BTODZ:h  
    +H-6eP  
    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: 6+|do+0Icg  
    1. 在FRED脚本编辑界面找到参考. 9igiZmM  
    2. 找到Matlab Automation Server Type Library m)t;9J5  
    3. 将名字改为MLAPP +>{2*\cZ5}

    z6=Z\P+  
    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。 RuA*YV

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /wEhVR`=  
    1. 创建Matlab服务器。 v5#j Z$<F  
    2. 移动探测面对于前一聚焦面的位置。 D9=KXo^  
    3. 在探测面追迹光线 *20jz<  
    4. 在探测面计算照度 q460iL7yF}  
    5. 使用PutWorkspaceData发送照度数据到Matlab x.!V^HQSN  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 XK3tgaH  
    7. 用Matlab画出照度数据 Z, Yb&b  
    8. 在Matlab计算照度平均值 {j?FNOJn  
    9. 返回数据到FRED中 $oID(P
