    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。 E'x"EN  
    ?+zFa2J  
    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: e,%|sAs[  
    enableservice('AutomationServer', true) ?%,LZw^[  
    enableservice('AutomationServer') lHM+<Z  
    24J c`%7,=  
    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 1jKpLTSs  
    )Cy>'l*Og7  
    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: !)bZ.1o  
    1. 在FRED脚本编辑界面找到参考. 5zK,(cF0-  
    2. 找到Matlab Automation Server Type Library gmVN(K}SR5  
    3. 将名字改为MLAPP \5a.JfF  
    'I,a 29  
    _r:Fmn_%-  
    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。 }m+Q(2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: uWJJ\  
    1. 创建Matlab服务器。 'KH+e#?Ar  
    2. 移动探测面对于前一聚焦面的位置。 OlT8pG5Oa  
    3. 在探测面追迹光线 w[X-Q+7p(t  
    4. 在探测面计算照度 x,C8):\t`B  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0/v]YK.  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 qSP &Fi  
    7. 用Matlab画出照度数据 D$>!vD'  
    8. 在Matlab计算照度平均值 ei-\t qY_  
    9. 返回数据到FRED中 .Y6v#VI
