    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。 4K:p  
    6EJ,czt(  
    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: iYBs )  
    enableservice('AutomationServer', true) 8L.Y0_x  
        enableservice('AutomationServer') |UE&M3S  
    2{g~6 U.  
    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 "w=.2A:q  
    KI#),~n S  
    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: H7*/  
    1. 在FRED脚本编辑界面找到参考. &R>x;&Gj  
    2. 找到Matlab Automation Server Type Library +ImPNwrY  
        3. 将名字改为MLAPP |5`z;u7V  
          H 2\KI(  
         =((#kDrN  
    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。 {dhGSM7

    3. 在探测面追迹光线 PO ]z'LD  
    4. 在探测面计算照度 6 O!&!  
    5. 使用PutWorkspaceData发送照度数据到Matlab u-yQP@^H  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 #:e52=  
    7. 用Matlab画出照度数据 +.NopI3:
