    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。 {wP|b@(1t  
    0f^.zt{T  
    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: \zU5G#LQ  
    enableservice('AutomationServer', true) p]&Q`oh  
    enableservice('AutomationServer') ]e.+u  
    %B*dj9n^q  
    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 =LxmzQO#

    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: \NU [DHrMP  
    1. 在FRED脚本编辑界面找到参考. mj=|oIMwT  
    2. 找到Matlab Automation Server Type Library n*~   
    3. 将名字改为MLAPP wF8\

    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。 3 \r@f_p

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |nN/x<v  
    1. 创建Matlab服务器。 AJfi,rFPg  
    2. 移动探测面对于前一聚焦面的位置。 j7#GqVS'  
    3. 在探测面追迹光线 K<6x4ha  
    4. 在探测面计算照度 k_<{j0z.  
    5. 使用PutWorkspaceData发送照度数据到Matlab [IFRwQ^%_O  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *t{c}Y&@  
    7. 用Matlab画出照度数据 2?iOB6  
    8. 在Matlab计算照度平均值 WG !t!1p  
    9. 返回数据到FRED中 4oV_b"xz~
