    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。 lVq5>:'}^;  
    -P|claO0  
    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: 8q{|nH  
    enableservice('AutomationServer', true) %`T}%B  
        enableservice('AutomationServer') IvkYM`%  
    1:^Xd~X  
    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 WwZ3hd  
    ){#INmsF  
    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: na~ FT[3 C  
    1. 在FRED脚本编辑界面找到参考. N6u>V~i  
    2. 找到Matlab Automation Server Type Library _6,\;"it?8  
        3. 将名字改为MLAPP #-f9>S9_  
         tA< UkPT  
         \<`oW>  
    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。 v6=%KXSF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: VY8cy2  
    1. 创建Matlab服务器。 [ei~Xkzkj  
    2. 移动探测面对于前一聚焦面的位置。 "]q xjs^3?  
    3. 在探测面追迹光线 BLaNS4e  
    4. 在探测面计算照度 /t7f5mA  
    5. 使用PutWorkspaceData发送照度数据到Matlab *w _o8!3-  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 zT6nC5E  
    7. 用Matlab画出照度数据 bfoTGi  
    8. 在Matlab计算照度平均值 wL, -"  
    9. 返回数据到FRED中 S#8)N`
