    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。 rfDGS%!O%  
    7FwtBO  
    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: qO@vXuul,  
    enableservice('AutomationServer', true) 4K cEJlK5  
    enableservice('AutomationServer') Zbo4{.#  
    %DuPM6 6r  
    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 T"\d,ug5[  
    (j>`+F5f  
    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: B7Ket8<J  
    1. 在FRED脚本编辑界面找到参考. w5Fk#zJv  
    2. 找到Matlab Automation Server Type Library \O*ZW7?TJ  
    3. 将名字改为MLAPP <MEm+8e/s6

    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。 MJX ny4n

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c:Czu  
    1. 创建Matlab服务器。 ]MCH]/  
    2. 移动探测面对于前一聚焦面的位置。 a;$V;3C{b&  
    3. 在探测面追迹光线 :r{-:   
    4. 在探测面计算照度 Ry[7PLn]  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q`i@['?p  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vU *: M8k  
    7. 用Matlab画出照度数据 6$#,$aO  
    8. 在Matlab计算照度平均值 .i\ FK@2  
    9. 返回数据到FRED中 c Lyf[z)W
