    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。 Pjh;;k|V  
    ZW?h\0Hh  
    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: J;>;K6pW  
    enableservice('AutomationServer', true) rTR$\ [C  
    enableservice('AutomationServer') V~PGmn[V  
    w#1BHx  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 #eYYu2ND  
    S(3h{Y"#  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ubB1a_7  
    1. 在FRED脚本编辑界面找到参考. k:n{AoUc  
    2. 找到Matlab Automation Server Type Library F+Kju2  
    3. 将名字改为MLAPP -$!r+4|q  
    l8E))oz1T  
    QV."ZhL5=  
    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。 #c:@oe4v

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Vw ;iE=L  
    1. 创建Matlab服务器。 1[OY- G  
    2. 移动探测面对于前一聚焦面的位置。 C+\z$/q  
    3. 在探测面追迹光线 ^%*qe5J  
    4. 在探测面计算照度 A23K!a2u&  
    5. 使用PutWorkspaceData发送照度数据到Matlab Hva!6vwO%O  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Zs^zD;zU  
    7. 用Matlab画出照度数据 t _ CMsp  
    8. 在Matlab计算照度平均值 (f"Qz~R|6_  
    9. 返回数据到FRED中  @mw1__?
