    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。 eB\r/B]  
    Zn/9BO5  
    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: <zf+Ii1:,  
    enableservice('AutomationServer', true) _5K_YhT  
    enableservice('AutomationServer') 8x9kF]=  
    $HXB !$d  
    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 =k*0O_  
    kR6 t .  
    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: (wlsn6h  
    1. 在FRED脚本编辑界面找到参考. XF7W'^  
    2. 找到Matlab Automation Server Type Library !Q(xOc9>Ug  
    3. 将名字改为MLAPP #pe{:f?  
    ^kl9U+  
    _ <;Q=?'*  
    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。 >4ct[fW+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ];I|_fXo%  
    1. 创建Matlab服务器。 ZM vTDH!  
    2. 移动探测面对于前一聚焦面的位置。 Hr+-ndH!Pq  
    3. 在探测面追迹光线 y\_S11{v  
    4. 在探测面计算照度 ii;WmE&  
    5. 使用PutWorkspaceData发送照度数据到Matlab p-pw*wH0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ILi5WuOYX  
    7. 用Matlab画出照度数据 NVj J/  
    8. 在Matlab计算照度平均值 R2$U K  
    9. 返回数据到FRED中 `oMeR]~
