    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。 x l=|]8w  
    _Fy:3,(  
    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: V t;&2v  
    enableservice('AutomationServer', true) 7O :Gi*MA  
        enableservice('AutomationServer') )@M|YM1+  
    K%_JQ0`  
    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 OZ9j3Q;a$  
    ')~HOCBSE  
    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: hmk5 1  
    1. 在FRED脚本编辑界面找到参考. f\w4F'^tj  
    2. 找到Matlab Automation Server Type Library T,@7giQg@  
        3. 将名字改为MLAPP >g=:01z9  
         $R36`wk  
         )+R3C%  
    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。 ( h,F{7

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  /t P  
    1. 创建Matlab服务器。 Mt0|`=64  
    2. 移动探测面对于前一聚焦面的位置。 |8ZAE%/d  
    3. 在探测面追迹光线 C.p*mO&N  
    4. 在探测面计算照度 CcE TS}Q0C  
    5. 使用PutWorkspaceData发送照度数据到Matlab EJY:C9W  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 BtZm_SeA  
    7. 用Matlab画出照度数据 cn{l %6K  
    8. 在Matlab计算照度平均值 Q"uu&JC  
    9. 返回数据到FRED中 !OemS 7{
