    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。 t&3 8@p  
    _@7(g(pY 3  
    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: w8O hJv  
    enableservice('AutomationServer', true) >}mNi:6xq  
    enableservice('AutomationServer') 6<#Slw[  
    &:-GI)[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 ]Kof sU_{

    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: :J<Owh@  
    1. 在FRED脚本编辑界面找到参考. )7tV*=?Ic8  
    2. 找到Matlab Automation Server Type Library e#K rgUG  
    3. 将名字改为MLAPP * q+oeAYX

    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。 ]Qh[%GD

    现在将脚本代码公布如下,此脚本执行如下几个步骤: H^ESA s6  
    1. 创建Matlab服务器。 |C^ c0  
    2. 移动探测面对于前一聚焦面的位置。 er#8D6*  
    3. 在探测面追迹光线 "4KkKi  
    4. 在探测面计算照度 ,"x23=]  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6Wf*>G*h  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 cAYa=}~<  
    7. 用Matlab画出照度数据 ys:1Z\$P  
    8. 在Matlab计算照度平均值 Og_2k ~  
    9. 返回数据到FRED中 *xEI Zx
