    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。 yX;v   
    r!J?Lc])8  
    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: [)83X\CO  
    enableservice('AutomationServer', true) X8=s k  
    enableservice('AutomationServer') ^DS+O>  
    $NhKqA`0  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 qlfYX8edZ  
    |{H-PH*Iz  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: m8njP-CZ  
    1. 在FRED脚本编辑界面找到参考. 7nL3+Pq  
    2. 找到Matlab Automation Server Type Library J2adA9R/,  
    3. 将名字改为MLAPP 5x; y{qT  
    1A b=1g{  
    :$>TeCm  
    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。 6dq*ncNin

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ');QmN%J  
    1. 创建Matlab服务器。 DEkFmmw   
    2. 移动探测面对于前一聚焦面的位置。 `CQMvX{  
    3. 在探测面追迹光线 C) "|sG  
    4. 在探测面计算照度 A 9HJWKO  
    5. 使用PutWorkspaceData发送照度数据到Matlab K@z zseQ}=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 '@<aS?@!t  
    7. 用Matlab画出照度数据 vS|uN(a.P  
    8. 在Matlab计算照度平均值 l ,T*b  
    9. 返回数据到FRED中 |4s`;4c&
