    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。 _3JTHf<+  
    ,\"gN5[$(  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: g DIB'Y  
    enableservice('AutomationServer', true) (b5af_ c  
    enableservice('AutomationServer') ;pYk+r6Cr  
    h{9 pr  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ]P5u:~U  
    *2hzReM  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 4\iQ%fb  
    1. 在FRED脚本编辑界面找到参考. H2-(  
    2. 找到Matlab Automation Server Type Library kv2:rmv  
    3. 将名字改为MLAPP o$;x[US  
    ".=EAXVU  
    <ZEll[0L  
    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。 1NJ|%+I

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =$J2  
    1. 创建Matlab服务器。 ponvi42u  
    2. 移动探测面对于前一聚焦面的位置。 4T-AWk  
    3. 在探测面追迹光线 qlP=Y .H  
    4. 在探测面计算照度 [sRQd;+  
    5. 使用PutWorkspaceData发送照度数据到Matlab '-qc \6UY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C7:Ry)8'I  
    7. 用Matlab画出照度数据 iddT.   
    8. 在Matlab计算照度平均值 -0Ek&"=Z^  
    9. 返回数据到FRED中 1:8: yFV
