    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。 PjNOeI@G  
    FjqoO.  
    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: *ndXZ64  
    enableservice('AutomationServer', true) HtB>#`'  
    enableservice('AutomationServer') Hj't.lg+j  
    NrT!&>M  
    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 dO}6zQ\  
    Y~#m-y  
    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: ec+&K?T  
    1. 在FRED脚本编辑界面找到参考. &2[OH}4  
    2. 找到Matlab Automation Server Type Library &^Q-:Kxs8  
    3. 将名字改为MLAPP  i1$ $86

    &?flH;  
    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。 .Nz2K[

    现在将脚本代码公布如下,此脚本执行如下几个步骤: L#mf[a@pCn  
    1. 创建Matlab服务器。 <VI.A" Qk~  
    2. 移动探测面对于前一聚焦面的位置。 ^N#B( F  
    3. 在探测面追迹光线 6U5L>sQ  
    4. 在探测面计算照度 IHHL. gT  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7{>mm$^|V  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @ -CZa^g  
    7. 用Matlab画出照度数据 X c~yr\%]  
    8. 在Matlab计算照度平均值 VWf&F`^B(
