    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。 /Sw~<B!8N  
    [a2]_]E%  
    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: 1;ttwF>G7  
    enableservice('AutomationServer', true) aDF@A S  
    enableservice('AutomationServer') 'f\9'v  
    #'_#t/u  
    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 yV(#z2|  
    }=[p>3Dd  
    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: s6,~J F^  
    1. 在FRED脚本编辑界面找到参考. y2jv84 M  
    2. 找到Matlab Automation Server Type Library DM^0[3XuV5  
    3. 将名字改为MLAPP '~D4%WKT  
    (p-q>@m  
    xsZG(Tz  
    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。 yE8D^M|g

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8G:/f3B=  
    1. 创建Matlab服务器。 jIubJQR~  
    2. 移动探测面对于前一聚焦面的位置。 #n>U7j9`O  
    3. 在探测面追迹光线 41X`.  
    4. 在探测面计算照度 1<r!9x9G  
    5. 使用PutWorkspaceData发送照度数据到Matlab ys9:";X;}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 r3'J{-kl  
    7. 用Matlab画出照度数据 72dRp!J U  
    8. 在Matlab计算照度平均值 4$xVm,n|  
    9. 返回数据到FRED中 ,a #>e
