    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。 q/EX`%U  
    jY=y<R_oK  
    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: YSP\+ZZ  
    enableservice('AutomationServer', true) /wJ#-DZ  
    enableservice('AutomationServer') & kC  
    c4fH/-  
    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 <P h50s4  
    q} e#L6cM  
    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: 7{ m>W!  
    1. 在FRED脚本编辑界面找到参考. cq I $9  
    2. 找到Matlab Automation Server Type Library |+ F ~zIu'  
    3. 将名字改为MLAPP t2d sYU/

    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。 <=.6Z*x+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 05wkUo:9  
    1. 创建Matlab服务器。 a=MN:s?Fc0  
    2. 移动探测面对于前一聚焦面的位置。 Q!l(2nva  
    3. 在探测面追迹光线 vb>F)X?b_  
    4. 在探测面计算照度 w/#7G\U  
    5. 使用PutWorkspaceData发送照度数据到Matlab "'v+*H 3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :s *  
    7. 用Matlab画出照度数据 ED` 1)1<  
    8. 在Matlab计算照度平均值 =8]`-(  
    9. 返回数据到FRED中 c(Dp`f,
