    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。 ].w~FUa  
    ?NWc3 .  
    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:  Jpm=V*P  
    enableservice('AutomationServer', true) NSI$uS6  
        enableservice('AutomationServer') _TEjB:9eY  
    hT go  
    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 aYW 9 C<5

    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: '*lVVeSiFw  
    1. 在FRED脚本编辑界面找到参考. ^ZuwUuuf  
    2. 找到Matlab Automation Server Type Library C%H{"  
        3. 将名字改为MLAPP ZOw%Fw4B

    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。 wNl{,aH@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /0CS2mLC  
    1. 创建Matlab服务器。 []OmztB  
    2. 移动探测面对于前一聚焦面的位置。 $Y`oqw?g+^  
    3. 在探测面追迹光线 gv\WI4"n  
    4. 在探测面计算照度 \:y oS>G  
    5. 使用PutWorkspaceData发送照度数据到Matlab %>Q[j`9y  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 \w#)uYK{i_  
    7. 用Matlab画出照度数据 XCvL`  
    8. 在Matlab计算照度平均值 v9*31Jx  
    9. 返回数据到FRED中 ?*LVn~y
