    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。 }WnoI2  
    u85?f  
    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: %`0*KMO3  
    enableservice('AutomationServer', true) gr\vC  
    enableservice('AutomationServer') 9)J)r \  
    bo[[<j!"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 `P jS  
    HY,VJxR[  
    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: 7VW/v4n  
    1. 在FRED脚本编辑界面找到参考. qJK-HF:#  
    2. 找到Matlab Automation Server Type Library hx hs>eY  
    3. 将名字改为MLAPP 4\y>pXML-U  
    4?Qc&e{5  
    xM13OoU  
    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。 >x8~?)7z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Ns6C xE9  
    1. 创建Matlab服务器。 9M7Wlx2  
    2. 移动探测面对于前一聚焦面的位置。 \ mg  
    3. 在探测面追迹光线 G\#dMCk?  
    4. 在探测面计算照度 NT<}-^  
    5. 使用PutWorkspaceData发送照度数据到Matlab ZU.f)94u  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #Ti5G"C  
    7. 用Matlab画出照度数据 /Y8{?  
    8. 在Matlab计算照度平均值 {jo"@&2S  
    9. 返回数据到FRED中 'J:xTp
