    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。 ,-4SVj8$P  
    o@p(8=x  
    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: 3)? v  
    enableservice('AutomationServer', true) 5BztOYn,  
        enableservice('AutomationServer') mnZS](>  
    \[nvdvJv  
    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 y<53xZi  
    t *8k3"  
    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: @[:JQ'R=  
    1. 在FRED脚本编辑界面找到参考. w<m) T  
    2. 找到Matlab Automation Server Type Library 3@d{C^\  
        3. 将名字改为MLAPP ,b&-o?.{  
         NI@$"   
         e:h(,  
    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。 I6k S1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c`hj^t  
    1. 创建Matlab服务器。 r35'U#VMk?  
    2. 移动探测面对于前一聚焦面的位置。 zW,Nv>Ac5  
    3. 在探测面追迹光线 (Wj2%*NT  
    4. 在探测面计算照度 &ye,A(4  
    5. 使用PutWorkspaceData发送照度数据到Matlab FqvMi:F  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 GN7\p)  
    7. 用Matlab画出照度数据 vlHE\%{  
    8. 在Matlab计算照度平均值 s+=JT+g  
    9. 返回数据到FRED中 ZL0':7
