    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。 aSHN*tP%y  
    HoWK# Nz\  
    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: Ze[\y(K!  
    enableservice('AutomationServer', true) ;9J6)zg !n  
        enableservice('AutomationServer') G-]_ d  
    b0se-#+  
    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 ?"?AH/ED

    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'~AyCn  
    1. 在FRED脚本编辑界面找到参考. 8hyX He  
    2. 找到Matlab Automation Server Type Library &rG]]IO  
        3. 将名字改为MLAPP MBQ|*}+;  
         $h=v ;1"  
         Hf30ve}  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 |^F$Ta

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $V/Ke  
    1. 创建Matlab服务器。 9c{ ~$zJW  
    2. 移动探测面对于前一聚焦面的位置。 0}9jl  
    3. 在探测面追迹光线 7s}F`fjKP  
    4. 在探测面计算照度 hOdU%  
    5. 使用PutWorkspaceData发送照度数据到Matlab $"0`2C  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 wg:\$_Og  
    7. 用Matlab画出照度数据 uOd1:\%*  
    8. 在Matlab计算照度平均值 Zl]@;*u  
    9. 返回数据到FRED中 eV;nTj
