    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。 j#"?Oe{_1  
    Xa.Qt.C  
    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: p)N=  
    enableservice('AutomationServer', true) q%w\UAqA  
    enableservice('AutomationServer') 3<1Uq3Pa  
    lplEQ]J|  
    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 "D'A7DA  
    @Nn9- #iW  
    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: _$s9o$8$  
    1. 在FRED脚本编辑界面找到参考. 8 qt,sU  
    2. 找到Matlab Automation Server Type Library t?L;k+sMM  
    3. 将名字改为MLAPP wbshKkUh_*  
    9Ruj_U  
    }+h/2D  
    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。 Q9H~B`\nQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Cb7f-Eag  
    1. 创建Matlab服务器。 zdrCr0Rx,  
    2. 移动探测面对于前一聚焦面的位置。 dq28Y$9~  
    3. 在探测面追迹光线 4pq@o  
    4. 在探测面计算照度 WLd{+y5#  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;t{Ew+s  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ^6bU4bA  
    7. 用Matlab画出照度数据 Q"n*`#Yt'  
    8. 在Matlab计算照度平均值 Jp=eh   
    9. 返回数据到FRED中 m{  .'55
