    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。 :k*'M U}  
    >-*rtiE  
    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: 1hp`.!3]H  
    enableservice('AutomationServer', true) `*g(_EZsS  
    enableservice('AutomationServer') ;4>YPH  
    ePv3M&\J  
    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 |r>+\" X

    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: zo6|1xq   
    1. 在FRED脚本编辑界面找到参考. *?x$q/a  
    2. 找到Matlab Automation Server Type Library Kkcb' aDR  
    3. 将名字改为MLAPP K|,P

    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。 H=RzY-\a%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: '9@S  
    1. 创建Matlab服务器。 C~-x637/  
    2. 移动探测面对于前一聚焦面的位置。 `?f6~$1  
    3. 在探测面追迹光线 ;-sZaU;  
    4. 在探测面计算照度 nWb*u  
    5. 使用PutWorkspaceData发送照度数据到Matlab .);~H#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C@d*t?  
    7. 用Matlab画出照度数据  bi/ AQ^  
    8. 在Matlab计算照度平均值 J_ NY:B  
    9. 返回数据到FRED中 P1C{G'cR
