    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。  <j_  
    l2LO,j}  
    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: 1eS@ihkP  
    enableservice('AutomationServer', true) t..@69  
    enableservice('AutomationServer') Vgj[m4l  
    ugW.nf*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 s*kSl:T @O  
    H"V)dEm  
    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: R"71)ob4  
    1. 在FRED脚本编辑界面找到参考. Op iVQr:  
    2. 找到Matlab Automation Server Type Library !8J%%Ux&M  
    3. 将名字改为MLAPP Y;sN UX

    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。 G^\.xk]

    2. 移动探测面对于前一聚焦面的位置。 kx[h41|n  
    3. 在探测面追迹光线 m\|ie8  
    4. 在探测面计算照度 ur/:aI  
    5. 使用PutWorkspaceData发送照度数据到Matlab s|Zv>Qt  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 uo^tND4a;j  
    7. 用Matlab画出照度数据 x#tP)5n?s*  
    8. 在Matlab计算照度平均值 7t/C:2^&  
    9. 返回数据到FRED中 'A#l$pJp7
