    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。 z5kAf~A  
    N% 4"9K  
    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: >#w;67he2  
    enableservice('AutomationServer', true) !R=@Nr>  
        enableservice('AutomationServer') $@>0;i ::  
    #;$]M4  
    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?H T'3)  
    );$99t  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: D5TDg\E  
    1. 在FRED脚本编辑界面找到参考. %up?70  
    2. 找到Matlab Automation Server Type Library O$<>v\NC?  
        3. 将名字改为MLAPP lH}KFFbp  
         )S caT1I  
         5o#JHD  
    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。 >2'"}np*

    1. 创建Matlab服务器。 FJ:^pROpm  
    2. 移动探测面对于前一聚焦面的位置。 *yu}e)(0  
    3. 在探测面追迹光线 |A%9c.DG.  
    4. 在探测面计算照度 V ~C$|+>e  
    5. 使用PutWorkspaceData发送照度数据到Matlab BAf$ty h  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 XBQt:7[<  
    7. 用Matlab画出照度数据 _)M,p@!?=h  
    8. 在Matlab计算照度平均值 =dmr ,WE  
    9. 返回数据到FRED中 c$O8Rhx
