    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。 K7qR  
    1F2(MKOo!  
    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: KlwB oC/{K  
    enableservice('AutomationServer', true) /(s N@kt  
        enableservice('AutomationServer') vsq |m 5  
    vBY?3p,0p  
    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 ~ /K'n  
    \)g}   
    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: !.|A}8nK  
    1. 在FRED脚本编辑界面找到参考. q(#,X~0  
    2. 找到Matlab Automation Server Type Library UD2 l!)rW  
        3. 将名字改为MLAPP 2XjH1  
         gHWsKE  %  
         P!&yYR\  
    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。 `,c~M

    2. 移动探测面对于前一聚焦面的位置。 B|AIl+y  
    3. 在探测面追迹光线 r8_MIGM'  
    4. 在探测面计算照度 ^w jMu5f  
    5. 使用PutWorkspaceData发送照度数据到Matlab CT=5V@_u\  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 f_.0 uM  
    7. 用Matlab画出照度数据 !,DA`Yt  
    8. 在Matlab计算照度平均值 BL\H@D
