    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。 "r46Rfa  
    9:p-F+  
    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: Y'iI_cg  
    enableservice('AutomationServer', true) yMWh#[phH  
    enableservice('AutomationServer') s $Vv  
    +51heuu[o  
    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 y.lWyH9

    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: b=r3WkB6  
    1. 在FRED脚本编辑界面找到参考. p=:Vpg<!  
    2. 找到Matlab Automation Server Type Library :\|A.# U  
    3. 将名字改为MLAPP 7(1`,Y  
    3SIq od;%  
    0Ncpi=6  
    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。 -8^qtB

    2. 移动探测面对于前一聚焦面的位置。 #VrIU8Q7'  
    3. 在探测面追迹光线 5;}W=x^$a  
    4. 在探测面计算照度 u0L-xC$L  
    5. 使用PutWorkspaceData发送照度数据到Matlab %]Z4b;W[Y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *#YZm>h   
    7. 用Matlab画出照度数据 J[<Zy^"Y;  
    8. 在Matlab计算照度平均值 w*6b%h%ww
