    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。 "uP*pR^  
    ~3-"1E>Rgy  
    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: @-L\c>rqT  
    enableservice('AutomationServer', true) FGPqF;  
        enableservice('AutomationServer') 3#x1(+c6  
    t*; KxQ+'?  
    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 ?hAO-*);  
    vz#-uw,O:  
    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: 7x77s  
    1. 在FRED脚本编辑界面找到参考. VxS3lR=  
    2. 找到Matlab Automation Server Type Library 5Ok3y|cEx  
        3. 将名字改为MLAPP Z"'*A\r2  
         r`"T{o\e   
         PjX V.gz  
    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。 *iY:R

    现在将脚本代码公布如下,此脚本执行如下几个步骤: p;'.7_1  
    1. 创建Matlab服务器。 t9MCT$U  
    2. 移动探测面对于前一聚焦面的位置。 ?-%(K^y4r  
    3. 在探测面追迹光线 tBfmjxv  
    4. 在探测面计算照度 r7].48D  
    5. 使用PutWorkspaceData发送照度数据到Matlab rW|%eT*/'A  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ,;5%&T  
    7. 用Matlab画出照度数据 PH&Qw2(Sx  
    8. 在Matlab计算照度平均值 2z" <m2 a  
    9. 返回数据到FRED中 O9-`e
