    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。 8j%lM/ v  
    `^E(P1oJ3  
    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: )3_g&&  
    enableservice('AutomationServer', true) *!(?=9[  
    enableservice('AutomationServer') ;/nR[sibN  
    \=g%W^i  
    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 "Zicac@N  
    |}roR{gc|  
    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:  )2,\Y  
    1. 在FRED脚本编辑界面找到参考. t#J #DyY5  
    2. 找到Matlab Automation Server Type Library Y)4D$9:  
    3. 将名字改为MLAPP (aH_K07  
    2|^bDg;W+u  
    ~Urj:l  
    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。 jZY9Lx8o

    现在将脚本代码公布如下,此脚本执行如下几个步骤: w4+bzdZ  
    1. 创建Matlab服务器。 whg?X&j\V  
    2. 移动探测面对于前一聚焦面的位置。 pRdO4?l  
    3. 在探测面追迹光线 1z(y>`ZBq  
    4. 在探测面计算照度 dQFx]p3L  
    5. 使用PutWorkspaceData发送照度数据到Matlab {z%%(,I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 eVWnD,'  
    7. 用Matlab画出照度数据 D9&FCCiUE  
    8. 在Matlab计算照度平均值 .es= w=  
    9. 返回数据到FRED中 93y.u<,2;
