    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。 QiBo]`)%  
    #&zNYzI  
    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: %D|p7&  
    enableservice('AutomationServer', true) uCGJe1!Ai>  
        enableservice('AutomationServer') \FOoIY!.x  
    gZbC[L  
    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 #~]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: i> Wsc?  
    1. 在FRED脚本编辑界面找到参考. A/eZnsk  
    2. 找到Matlab Automation Server Type Library J`/t;xk  
        3. 将名字改为MLAPP zzlV((8 ~  
         67Z@Hg  
         ;"/[gFD5u  
    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。 "b)Y5[nW

    3. 在探测面追迹光线 T](N ^P  
    4. 在探测面计算照度 #O3Y#2lI  
    5. 使用PutWorkspaceData发送照度数据到Matlab fyYHwG  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 >fG=(1"  
    7. 用Matlab画出照度数据 N.r8dC  
    8. 在Matlab计算照度平均值 s|*0cK!K^  
    9. 返回数据到FRED中 N|t!G^rP
