    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。 gH/k}M7tA#  
    cGjkx3l*  
    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: ^kj%Ekt7  
    enableservice('AutomationServer', true) Bk~M^AK@~  
    enableservice('AutomationServer') a^&3?3   
    = G3A}  
    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&;,$KDA  
    h'G8@j;  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: q0 8  
    1. 在FRED脚本编辑界面找到参考. SkA"MhX  
    2. 找到Matlab Automation Server Type Library fBt7#Tc=U  
    3. 将名字改为MLAPP OAz -w  
    #Y<b'7yJ  
    aMjCqu05  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 eM`"$xc Oe

    现在将脚本代码公布如下,此脚本执行如下几个步骤: nyB~C7zR  
    1. 创建Matlab服务器。 `{I-E5 x  
    2. 移动探测面对于前一聚焦面的位置。 l,3[hx  
    3. 在探测面追迹光线 RpY#_\^hI  
    4. 在探测面计算照度 Yt;.Z$i ,  
    5. 使用PutWorkspaceData发送照度数据到Matlab !b+Kasss9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 yf6&'Y{  
    7. 用Matlab画出照度数据 n-_-;TYH  
    8. 在Matlab计算照度平均值 Djf,#&j!3  
    9. 返回数据到FRED中 [HENk34
