    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。 qJY'"_Q{  
    II !Nr{A  
    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: jS LNQ  
    enableservice('AutomationServer', true) |P{K\;-  
        enableservice('AutomationServer') ~&>|u5C*@  
    pkd#SY  
    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 9,h'cf`F  
    yH\z+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: OGgP~hd  
    1. 在FRED脚本编辑界面找到参考. QLx]%E\  
    2. 找到Matlab Automation Server Type Library h,:8TMJRRN  
        3. 将名字改为MLAPP 1 J3h_z6/

    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。 $O}:*.{(W

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %i!&Fr  
    1. 创建Matlab服务器。 Tv d=EO  
    2. 移动探测面对于前一聚焦面的位置。 ET ;=o+\d  
    3. 在探测面追迹光线 5ZG-3qj  
    4. 在探测面计算照度 ,j{$SuZ M  
    5. 使用PutWorkspaceData发送照度数据到Matlab `4 Jlf!  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 v!oXcHK/  
    7. 用Matlab画出照度数据 7x *]  
    8. 在Matlab计算照度平均值 IuJj ;L1  
    9. 返回数据到FRED中 B+y r 6Q.
