    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。 ,XDRO./+T  
    Q></`QWpoB  
    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: ~t9tnLc$  
    enableservice('AutomationServer', true) pRkP~ZISU  
    enableservice('AutomationServer') Xs: 3'ua  
    OnQdq^UB  
    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 [ ol9|sdu  
    T,aW8|  
    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: Z}$TKO*u  
    1. 在FRED脚本编辑界面找到参考. BauU{:Sh  
    2. 找到Matlab Automation Server Type Library F*"}aP$  
    3. 将名字改为MLAPP okbQ<{9  
    7}M2bH} \K  
    /|* Y2ETOr  
    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。 lXcx@#~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: : q#Xq;Wp  
    1. 创建Matlab服务器。 DI+fwXeg  
    2. 移动探测面对于前一聚焦面的位置。 CrwwU7qKL  
    3. 在探测面追迹光线 ,l<6GB2\  
    4. 在探测面计算照度 B95B|tU>.  
    5. 使用PutWorkspaceData发送照度数据到Matlab ")d`dj\o  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 0`^&9nR  
    7. 用Matlab画出照度数据 0#nPbe,Lj  
    8. 在Matlab计算照度平均值 ,7<f9 EVY  
    9. 返回数据到FRED中 Q%xC}||1s"
