    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。 sIQMUC[!  
     t}* qs  
    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: -qr:c9\px  
    enableservice('AutomationServer', true) ).@)t:uNa  
    enableservice('AutomationServer') :7'0:'0$t  
    8?]%Q 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 jw6ng>9  
    +eVpMD( l  
    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: %'p|JS  
    1. 在FRED脚本编辑界面找到参考. *jqPKK/  
    2. 找到Matlab Automation Server Type Library //@sktHsw(  
    3. 将名字改为MLAPP :5qqu{GL  
    9EY_R&Yq%  
    [eTck73  
    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。 [s& y_[S

    现在将脚本代码公布如下,此脚本执行如下几个步骤: kA->xjk  
    1. 创建Matlab服务器。 o::ymAj  
    2. 移动探测面对于前一聚焦面的位置。 iJ~iJ'vf  
    3. 在探测面追迹光线 9/^Bj  
    4. 在探测面计算照度 ;L/T}!Dx  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1OJD\wc  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1QdB`8in  
    7. 用Matlab画出照度数据 OYCFx2{  
    8. 在Matlab计算照度平均值 }j5@\c48  
    9. 返回数据到FRED中 A'P}mrY
