    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。 C*9m `xh  
    8/CGg_C1  
    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: ec=C7M |  
    enableservice('AutomationServer', true) pV!(#45~W  
    enableservice('AutomationServer') k[p  
    =aCv Xa&,  
    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 [D)A+

    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: wmIq{CXx,  
    1. 在FRED脚本编辑界面找到参考. Y5 dt?a  
    2. 找到Matlab Automation Server Type Library &~& i >  
    3. 将名字改为MLAPP b6lL8KOu

    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。 p d6d(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: cZYX[.oIB  
    1. 创建Matlab服务器。 Rq 7ksTo  
    2. 移动探测面对于前一聚焦面的位置。 +[F8>9o&  
    3. 在探测面追迹光线 jmIP c3O0  
    4. 在探测面计算照度 Q3D xjD  
    5. 使用PutWorkspaceData发送照度数据到Matlab =[WccF  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 O ?4V($  
    7. 用Matlab画出照度数据 'Zzm'pC  
    8. 在Matlab计算照度平均值 \rJk[Kec  
    9. 返回数据到FRED中 -[F^~Gv|;
