    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。 L. ?dI82c  
    qCT\rZU  
    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: *J5euA5=  
    enableservice('AutomationServer', true) 4gt "dfy+  
        enableservice('AutomationServer') 3sIM7WD?  
    ;AA7wK 4  
    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%_ :(  
    lD=j/    
    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: yp'>+cLa  
    1. 在FRED脚本编辑界面找到参考. JU+'UK630  
    2. 找到Matlab Automation Server Type Library mV]g5>Q\  
        3. 将名字改为MLAPP ]Y! Vyn  
         ai9,4  
         $F$R4?_  
    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。 4?uG> ;V

    现在将脚本代码公布如下,此脚本执行如下几个步骤: r}Av"  
    1. 创建Matlab服务器。 =xP{f<`   
    2. 移动探测面对于前一聚焦面的位置。 mQuaO# I,  
    3. 在探测面追迹光线 4'| :SyOm  
    4. 在探测面计算照度 "$YLU}S9  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1D DOUV  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 HKw4}FC*  
    7. 用Matlab画出照度数据 BVeNK=7m%  
    8. 在Matlab计算照度平均值 xGk4KcxKs  
    9. 返回数据到FRED中 h(up1(x
