    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。 {rZ"cUm  
    !U_L7  
    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: %5%Wo(W'  
    enableservice('AutomationServer', true) TXcKuo=  
    enableservice('AutomationServer') YW<2:1A|  
    ]aNnY?qW5  
    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 UD{/L"GG

    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: F]YKYF'1I  
    1. 在FRED脚本编辑界面找到参考. Ef.4.iDJrR  
    2. 找到Matlab Automation Server Type Library \]xYV}(FO  
    3. 将名字改为MLAPP M;qL)vf

    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。  #Uh 5tc

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :N*T2mP  
    1. 创建Matlab服务器。 j_@3a)[NY  
    2. 移动探测面对于前一聚焦面的位置。 C4]%pi  
    3. 在探测面追迹光线 x-&v|w'  
    4. 在探测面计算照度 v Lv@Mo  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^z^e*<{WEl  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 OPW"AB J  
    7. 用Matlab画出照度数据 (JW?azU  
    8. 在Matlab计算照度平均值 ]0 RXo3  
    9. 返回数据到FRED中 RWCS u$
