    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。 *g}(qjl<  
    >k6RmN  
    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: %n3lm(-0U  
    enableservice('AutomationServer', true) BPoY32d"_  
    enableservice('AutomationServer') 7>g^OE f  
    2BU%4IG  
    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 vGK'U*gGD  
    (f^K\7HM  
    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: 3w=OvafT:  
    1. 在FRED脚本编辑界面找到参考. ?lh `>v  
    2. 找到Matlab Automation Server Type Library ddDl~&}o  
    3. 将名字改为MLAPP \\F@_nB,b  
    !+?,y/*5(  
    O\64)V 0  
    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。 [dje!5Dc(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >Lh+(M;+F  
    1. 创建Matlab服务器。 cxhS*"Ph  
    2. 移动探测面对于前一聚焦面的位置。 TSQ/{=r  
    3. 在探测面追迹光线 a *n^(  
    4. 在探测面计算照度 P"`OuN  
    5. 使用PutWorkspaceData发送照度数据到Matlab {iGk~qN  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1M|DaAI  
    7. 用Matlab画出照度数据 *&b~cyC
