    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。 8>y!=+9_  
     }FoO  
    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: >84:1 `  
    enableservice('AutomationServer', true) dDoKmuY>5  
    enableservice('AutomationServer') Hjtn*^fo^  
    ( @y te  
    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 _>"f&nb O  
    95%, 8t  
    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: (iw)C)t*u  
    1. 在FRED脚本编辑界面找到参考. Z 71.*  
    2. 找到Matlab Automation Server Type Library Q+]9Glz9  
    3. 将名字改为MLAPP X_nxC6[m%  
    -g;cg7O#(  
    f.cQp&&]r  
    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。 [O52Bn

    1. 创建Matlab服务器。 g.re`m|Aj  
    2. 移动探测面对于前一聚焦面的位置。 c7fQ{"f 3B  
    3. 在探测面追迹光线 "o ^cv  
    4. 在探测面计算照度 #=* y7w  
    5. 使用PutWorkspaceData发送照度数据到Matlab {zf)im[.  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 V<+= t{  
    7. 用Matlab画出照度数据 'QrvkQ  
    8. 在Matlab计算照度平均值 It .`  
    9. 返回数据到FRED中 F3L'f2yBG
