    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。 c; MF  
    0afDqvrC6  
    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: as k76  e  
    enableservice('AutomationServer', true) <*Ex6/j  
        enableservice('AutomationServer') {hNvCk  
    #^] v5s  
    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 =_"[ &^

    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: 0DZ}8"2  
    1. 在FRED脚本编辑界面找到参考. Q4[^JQsR2  
    2. 找到Matlab Automation Server Type Library 4 g%BCGsys  
        3. 将名字改为MLAPP #Bih=A #  
         5gg Yg $  
         rsGQ :c  
    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。 iPuX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 7gx 7NDt  
    1. 创建Matlab服务器。 'f "KV|  
    2. 移动探测面对于前一聚焦面的位置。 L3@upb  
    3. 在探测面追迹光线 .^F(&c*['  
    4. 在探测面计算照度 4[.DQ#r  
    5. 使用PutWorkspaceData发送照度数据到Matlab Pw :{  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 f)b+>!  
    7. 用Matlab画出照度数据 -,Oq=w*EV  
    8. 在Matlab计算照度平均值 2BGS$$pP  
    9. 返回数据到FRED中 &hSABtr}
