    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。 A4^+p0@  
    AjS5  
    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: 4j*}|@x  
    enableservice('AutomationServer', true) hG67%T'}A  
    enableservice('AutomationServer') Y `{U45  
    wfdFGoy(  
    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 o6r4tpiR5  
    gM*s/,;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: p#kC#{<nE  
    1. 在FRED脚本编辑界面找到参考. $1v5*E  
    2. 找到Matlab Automation Server Type Library 4|(?Wt)5  
    3. 将名字改为MLAPP x\%eg w  
    { nV zN(  
    \x!>5Z Y  
    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。 oxzNV&D[{`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: r)t^qhn  
    1. 创建Matlab服务器。 u!i5Q  
    2. 移动探测面对于前一聚焦面的位置。 'GFzI:Xr  
    3. 在探测面追迹光线 /\#5\dHj  
    4. 在探测面计算照度 vf2K2\fn  
    5. 使用PutWorkspaceData发送照度数据到Matlab Y8PT`7gd`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +6=!ve}  
    7. 用Matlab画出照度数据 xR:h^S^W ~  
    8. 在Matlab计算照度平均值 #jX>FXo  
    9. 返回数据到FRED中 ~K9U0ypH
