    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。 ~7an j.  
    z]7/Gc,j  
    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: Dxy^r*B  
    enableservice('AutomationServer', true) J$5Vjh'aM  
    enableservice('AutomationServer') |az2vD6P  
    v7 n@CWnN  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ,l Y4WO  
    c?N,Cd~q  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: .5uqc.i"f  
    1. 在FRED脚本编辑界面找到参考. F$bV}>-1k  
    2. 找到Matlab Automation Server Type Library h+ud[atk.  
    3. 将名字改为MLAPP /3&MUB*z&y  
    |{v#'";O:  
    | kP utB  
    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。 P?S]Q19Q4

    1. 创建Matlab服务器。 hJsP;y:@Lm  
    2. 移动探测面对于前一聚焦面的位置。 )U=]HpuzI  
    3. 在探测面追迹光线 T7%!JBg@  
    4. 在探测面计算照度 LT"H -fTgs  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^GyZycch  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $xWUzg1<U  
    7. 用Matlab画出照度数据 vd)zvI  
    8. 在Matlab计算照度平均值 \5 rJ  
    9. 返回数据到FRED中 k/D{&(F ~
