    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。 /| f[us-w  
    c!~T2t  
    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: #11RLvDQd  
    enableservice('AutomationServer', true) P CsK()  
    enableservice('AutomationServer') VKf6|ae  
    86{ZFtv  
    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 sS'{QIRC'  
    "3ug}k  
    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: YE_6OLW  
    1. 在FRED脚本编辑界面找到参考. \4@a  
    2. 找到Matlab Automation Server Type Library -R74/GBg  
    3. 将名字改为MLAPP \P?--AI q<  
    Fo LDMx(  
    "s;ci~$  
    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。 9F)W19i.

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ax]9QrA  
    1. 创建Matlab服务器。 U TS{H  
    2. 移动探测面对于前一聚焦面的位置。 #8&#E?^d  
    3. 在探测面追迹光线 ^@N`e1  
    4. 在探测面计算照度  2+Vp'5>&  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]]3Q*bq4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?M]u$Te/.  
    7. 用Matlab画出照度数据 ex:3ua$N  
    8. 在Matlab计算照度平均值 p Mh++H]"  
    9. 返回数据到FRED中 'Dq"e$JM<
