    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。 rocB"0  
    Q+d.%qhc  
    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: 8pPC 9ew\=  
    enableservice('AutomationServer', true) X&(ERY,h  
    enableservice('AutomationServer') z]c,} Q  
    /S]:dDY9K  
    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 hDljY!P>p

    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: \- =^]]b=  
    1. 在FRED脚本编辑界面找到参考. *`ZB+ \*  
    2. 找到Matlab Automation Server Type Library 'B3Wza.  
    3. 将名字改为MLAPP S,9NUt

    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。 +YkW[a\4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: oWp}O?  
    1. 创建Matlab服务器。 m_m8c8{Y  
    2. 移动探测面对于前一聚焦面的位置。 rFmKmV  
    3. 在探测面追迹光线 %j'G.*TD  
    4. 在探测面计算照度 =#i4MXRZ{  
    5. 使用PutWorkspaceData发送照度数据到Matlab X,TTM,1w  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 =.36y9Mfo  
    7. 用Matlab画出照度数据 K`QOU-M@}  
    8. 在Matlab计算照度平均值 lt{lpH  
    9. 返回数据到FRED中 Y=vVxVI\
