    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。 Hr;h4J  
    KB{RU'?f|  
    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: `ia %)@  
    enableservice('AutomationServer', true) 1S%k  
        enableservice('AutomationServer') 3bC yTZk  
    eN0P9.eqM  
    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 bv?0.{Z

    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: {}e^eJ  
    1. 在FRED脚本编辑界面找到参考. pL oy  
    2. 找到Matlab Automation Server Type Library V7CoZnz  
        3. 将名字改为MLAPP M\/XP| 7

    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。 ru.5fQ U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 34C``i  
    1. 创建Matlab服务器。 H^c0Kh+  
    2. 移动探测面对于前一聚焦面的位置。 #*IVlchA"B  
    3. 在探测面追迹光线 f %fa{  
    4. 在探测面计算照度 D\L!F6taS  
    5. 使用PutWorkspaceData发送照度数据到Matlab tR`S#rk  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 I{.HO<$7D}  
    7. 用Matlab画出照度数据 ='Oj4T  
    8. 在Matlab计算照度平均值 Q49BU@xX  
    9. 返回数据到FRED中 9$WJ"]
