    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。 Zu[su>\  
    C,r;VyW6BI  
    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: Qw*|qGvy^  
    enableservice('AutomationServer', true) (L&d!$,Dv  
    enableservice('AutomationServer') q|(HsLs  
    W ac&b  
    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 :5<UkN)R(  
    k y7Gwc  
    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: \R_C&=  
    1. 在FRED脚本编辑界面找到参考. x 9fip-  
    2. 找到Matlab Automation Server Type Library a;+9mDXx:  
    3. 将名字改为MLAPP ;A*]l' [-  
    a1lh-2x X  
    ?6U0PChy  
    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。 NXrlk

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0GeTS Fj  
    1. 创建Matlab服务器。 rV#ch(  
    2. 移动探测面对于前一聚焦面的位置。 onzxx4bax  
    3. 在探测面追迹光线 3s#N2X;Bc  
    4. 在探测面计算照度 ;e*!S}C,  
    5. 使用PutWorkspaceData发送照度数据到Matlab q_58;Bv  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 q/,O\,  
    7. 用Matlab画出照度数据 Q![@c   
    8. 在Matlab计算照度平均值 ~]2K ^bh8&  
    9. 返回数据到FRED中 sXPe/fWo
