    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。 TRo4I{L6S  
    ,;c{9H  
    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: =:;YTie  
    enableservice('AutomationServer', true) *n,UOHlO  
    enableservice('AutomationServer') 7fUi?41XA  
    7Y)s#FJ  
    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 {vjq y&?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: -h=c=P  
    1. 在FRED脚本编辑界面找到参考. LK{a9` h  
    2. 找到Matlab Automation Server Type Library uV!MW=)  
    3. 将名字改为MLAPP ea>[BB3#  
    FGDw;lEa9[  
    #c :9 V2  
    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。 |fx#KNPf]

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9Y\F53p&j  
    1. 创建Matlab服务器。 w9'H.L q  
    2. 移动探测面对于前一聚焦面的位置。 ^fG`DjA)  
    3. 在探测面追迹光线 [q w  
    4. 在探测面计算照度 k-io$  
    5. 使用PutWorkspaceData发送照度数据到Matlab s!NisF  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "i}Z(_7yr  
    7. 用Matlab画出照度数据 B{^`8Htrn  
    8. 在Matlab计算照度平均值 X4XFu  
    9. 返回数据到FRED中 #%;<FFu\
